One angle of a triangle has a measure of 36°. The measure of the third angle is 28° less than 3 times the measure of the second

Alex_Xolod [135]

Answer:

Define your variable and write your equation: 36 + b + (3b-28) = 180°.
measure of the second angle: 43°.
measure of the third angle: 101°

Step-by-step explanation:

a = 36

c = 3b - 28

a + b + c = 180°

a = measure of the first angle

b = measure of the second angle

c = measure of the third angle

then:

1) 36 + b + (3b-28) = 180 ⇒ )Define your variable. Write your equation and solve)

b + 3b + 36 - 28 = 180

4b + 8 = 180

4b = 180 - 8

4b = 172

b = 172/4

2) b = 43° ⇒ measure of the second angle

c = 3b - 28

c = 3*43 - 28

c = 129 - 28

3) c = 101° ⇒ measure of the third angle

Check:

36° + 43° + 101° = 180°

Simplify 36x^4 42x^7

Alja [10]

The first step to simplify this equation is to multiply the numbers
1512 $x^{4}$ × $x^{7}$
next,, youll multiply the terms with the same base by adding their exponents
1512 $x^{4+7}$
finally,, youll add the numbers together
1512 $x^{11}$
since you cant simplify any further,, the correct answer to your question is 1512 $x^{11}$
let me know if you have any further questions
