Step-by-step explanation:
In triangle DEF, m∠D = (4x + 15)°, m∠E = (5x + 32)°, and m∠F = 70°. Determine the degree measure of the exterior angle to ∠D.
137°
113°
67°
43°
The measure of the exterior angle to ∠D will be 137°.
What is mean by Triangle?
A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
In triangle DEF,
m ∠D = (4x + 15)°, m ∠E = (5x + 32)°, and m ∠F = 70°
Now,
Sum of the measure of angle in a triangle is 180°.
So, We can formulate;
⇒ m ∠D + m ∠E + m ∠F = 180°
Substitute all the values, we get;
⇒ (4x + 15) + (5x + 32) + 70 = 180
⇒ 9x + 117 = 180
⇒ 9x = 180 - 117
⇒ 9x = 63
⇒ x = 7
Thus, We get;
m ∠D = (4x + 15)°
m ∠D = (4 x 7 + 15)°
m ∠D = (28 + 15)°
m ∠D = (43)°
And, m ∠E = (5x + 32)°
m ∠E = (5 x 7 + 32)°
m ∠E = (35 + 32)°
m ∠E = 67°
Since, The measure of the exterior angle to ∠D = m ∠E + m ∠F
= 67° + 70°
= 137°
Thus, The measure of the exterior angle to ∠D will be 137°.

Answer:
Step-by-step explanation:
let amount of nickels = y
then amount of quarters = 12-y
let amount of dimes = 2y
according to given condition,
Total amount = y+12-y+2y
we will +y and -y because of different signs,(+,- = -).
10.60 = 12+2y
12-10.60 = 2y
2.60=2y
using / as division sign,
y=2.60/2
y = 1.30
amount of quarters = 1.30
amount of nickels = 12-y
= 12-1.30
= 10.70
amount of dimes = 2y
=2(1.30)
=2.60

write each of the following expressions as a power of two (4x2^5)\(2^3x1/16)
P.S. the x is a multiplication sign not a variable
Answer:
Step-by-step explanation:
Rewrite as : (2^2 * 2^5) / (2^3 * 2^4)
= 2^7 / 2^(-1)
Note: Based on exponent rules you do 2 power 7 minus, minus seven. And 2 minus is a positive. So you do 2 power seven plus 2 power 1. That is 2 power 8.

Answer:
The lengths of AB and EF are 10 and 2 respectively
Step-by-step explanation:
The lengths of AB and EF are 10 and 2 respectively
If the triangle ABC and DEF are similar, based on the similarity theorem of a triangle;
AB/DE = BC/EF
5x/4 = 5/x
5x² = 20
x² = 20/5
x² = 4
x = 2
Since the value of x is 2, length of AB is 5x = 5(2) = 10
Since EF = x, hence EF = 2
The lengths of AB and EF are 10 and 2 respectively
