Answer:

x=13

Step-by-step explanation:

one angle of triangle=85

parallel lines and vertical angles

the second angle is 82:

sum of angles of the triangle=180

x+85+82=180

x+167=180

x=180-167

x=13

Simplify. -x/17 = -0.9<br> a. -15.3<br> b. 15.3<br> c. 153<br> d. -153

Answer:

$\large\boxed{b.\ 15.3}$

Step-by-step explanation:

$-\dfrac{x}{17}=-0.9\qquad\text{multiply both sides by (-17)}\\\\(-17\!\!\!\!\!\diagup^1)\left(-\dfrac{x}{17\!\!\!\!\!\diagup_1}\right)=(-17)(-0.9)\qquad{/(-)(-)=(+)/}\\\\x=15.3$

Find the value of each measure.

zloy xaker [14]

The two congruent base angles tell us that this is an isosceles triangle, meaning the triangle has two congruent sides. Therefore, we can set these two expressions equal to each other and solve from there.

15x + 7 = 23x - 17

7 = 8x - 17

8x = 24

x = 3

Side = 15(3) + 7 = 45 + 7 = 52

Hope this helps!
