The measure of <Y is 38.
What is Angle Sum Property?According to the triangle's "angle sum property," a triangle's angles add up to 180 degrees. Three sides and three angles, one at each vertex, make up a triangle. The sum of the interior angles in a triangle is always 180, regardless of whether it is acute, obtuse, or right.
One of the most commonly applied properties in geometry is the triangle's angle sum property.
Given:
m∠X = 47°, m∠Y = (2x − 18)°, and m∠Z = (5x − 45)°.
Using angle sum property
m<X + m<Y + m<Z = 180
47 + 2x- 18 + 5x - 45= 180
7x -16=180
7x= 180+16
7x= 196
x= 196/7
x= 28
So, the measure of <Y = 2x- 18 = 2(28) - 18 = 56-18 = 38
Hence, the measure of <Y is 38.

Select and solve the inequality
Ryan is a wrestler trying to make weight. He currently weighs 200 lbs. If he cuts 2 lbs. per week, how many full weeks will it take him to weigh less than 175 lbs.? Choose an inequality below and solve it.
2w+175 <200 -2w+ 200 < 175
-2w+ 200 175 -2w+ 200 > 175
a.) 13 weeks b.) 12 weeks c.) 14 weeks d.) 10 weeks
Answer:
Step-by-step explanation:
The correct option is C More than 12.5 Weeks Let x be the number of weeks, then 200 − 2 x < 175 ⇒ 2 x > 200 − 175 ⇒ 2 x > 25 ⇒ x > 12.5 So, More than 12.5 Weeks is the answer.
ANSWER 12
Answer:
Step-by-step explanation:
A.13w, 13 weeks will get him down to 174lbs, 12 weeks would only get him 176lbs, so the minimum/full amount of weeks he needs to get down to less than 175lbs is 13.
Equation:
w=2
13w=26
200-26=174.

BCD is a straight line.
Triangle ABC is equilateral.
CE=DE
Work out the size of angle x.
The size of angle x is 44°.
Each equilateral triangle angle is measured at 60°.
∠ACB = 60°.
If two triangle sides are congruent, then the angles opposite those sides are also congruent.
∠CDE = ∠DCE
According to Angle Sum Theorem: ∠CDE + ∠CED + ∠DCE = 180°.
Substitute ∠CDE = ∠DCE into ∠CDE + ∠CED + ∠DCE = 180°
∠DCE + 28° + ∠DCE = 180°
∠DCE = 76°
The Angle Addition Postulate and the notion of a straight angle:
∠ACB + ∠ACE + ∠DCE = 180°
Substitute ∠ACE = x, ∠ACB = 60, ∠DCE = 76 into ∠ACB + ∠ACE + ∠DCE = 180°
60° + x + 76° = 180°
x = 44°

Answer:
b = 7
Step-by-step explanation:
using the rule of exponents
[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m+n)}[/tex] , then
[tex](-14)^{8}[/tex] × [tex](-14)^{b}[/tex] = [tex](-14)^{15}[/tex]
[tex](-14)^{(8+b)}[/tex] = [tex](-14)^{15}[/tex]
since the bases on both sides are equal, both - 14, then equate exponents
8 + b = 15 ( subtract 8 from both sides )

For triangle XYZ, m∠X = (7g + 12)° and the exterior angle to ∠X measures (2g + 60)°. Find the measure of ∠X and its exterior angle.
Interior angle = 49°; exterior angle = 131°
Interior angle = 131°; exterior angle = 49°
Interior angle = 96°; exterior angle = 84°
Interior angle = 84°; exterior angle = 96°
Step-by-step explanation:
the sum of the interior and the exterior angle must be 180°.
7g + 12 + 2g + 60 = 180
9g + 72 = 180
9g = 108
g = 12
interior angle = 7×12 + 12 = 96°
exterior angle = 2×12 + 60 = 84°
There is a of cubes. Stage I has 1 cube, Stage II has 4 cubes, and stage III has 10 cubes. How many cubes will there be in Stage IX?
There are 135 cubes will be there in stage IX.
What is cube?A cube is indeed a three-dimensional solid object in geometry that is surrounded by six square faces, facets, or sides, three of which meet at each vertex. One of the five Platonic solids, the cube seems to be the only regular hexahedron. It has 8 vertices, 6 faces, and 12 edges.
Given:
There is a of cubes.
Stage I has 1 cube, stage II has 4 cubes and stage III has 10 cubes.
So, we add 3, 6, 9 that means multiple of cubes in each stage.
So, the fourth stage has 10 + 9 = 19 cubes.
Stage IV has 19 + 12 = 31 cubes.
Stage V has 31 + 15 = 46 cubes.
Stage VI has 46 + 18 = 64 cubes.
Stage VII has 64 + 21 = 85 cubes.
Stage VIII has 85 + 24 = 109 cubes.
Stage IX has 109 + 27 = 136 cubes.
Therefore, there are 136 cubes will be there in Stage IX.
