Answer:
x = 3
Measurement of angle b: 70 degrees
Measurement of angle c: 70 degrees
Step-by-step explanation:
120° = (15x + 5) + (22x + 4) (ext. ∠ of △)
120° = 15x + 22x + 5 + 4
(120 - 9)° = 37x
x = (111/37)
x = 3
Measurement of angle b: 22x = 4 = 22(3) + 4 = 66 + 4 = 70 degrees
Measurement of angle c: 15x + 5 = 15(3) + 5 = 45 + 5 = 50 degrees
Hope this helped!
Answer:
x = 3, ∠ B = 70°, ∠ C = 50°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ ADC is an exterior angle of the triangle , then
15x + 5 + 22x + 4 = 120 , that is
37x + 9 = 120 ( subtract 9 from both sides )
37x = 111 ( divide both sides by 37 )
x = 3
Thus
∠ B = 22x + 4 = 22(3) + 4 = 66 + 4 = 70°
∠ C = 15x + 5 = 15(3) + 5 = 45 + 5 = 50°

Answer:
so one thing you can do is to put the standard form into slope-intercept form
so 6x+y= -4 into y=-6x -4
now, you put a point on (0,-4)
(x,y)
now the slope is -6/1 so you rise (go down) -6 points and run (sideways) 1

Answers
Answer:
1. 128
2. 52
3. 47
4. 133
5. 81
Step-by-step explanation:
1. <1 and <52 are same side interior angles, therefore supplementary. So they should add up to equal 180, this means that <1 is 180 - 52. Solve to get <1 is 128
2. <2 is an alternate interior angle to <52, this means that they are congruent. Since they are congruent, they have the same value of 52.
3. <3 is an alternate interior angle to <47, so they are congruent, this means that they both have a value of 47
4. <4 is supplementary to <3 so you can say that <4 is equal to 180 - 47. Solve this to get <4 is 133
5. <5, <52, and <47 are supplementary when you combine all three. So you can create an equation that says <5 is equal to 180 - 52 + 47. This gives you that angle 5 is 81.

Hope this helps!
Merry Christmas!
Answer:
By using the Pythagorean theorem we can solve this
The Pythagorean theorem states that [tex]c^2=a^2+b^2[/tex] where c is the hypotenuse (longest side of the right triangle) and a and b are the other 2 sides. LEts use x to represent the missing side
Therefore,
[tex]25^2=24^2+x^2[/tex]
[tex]625=576+x^2[/tex]
[tex]625-576=576-576+x^2[/tex]
