-1 is correct answer because
a= -2
b= 5 then
(-2^2-5)^3
(4-5)^3
(-1)^3
-1
x + 2x + 8 − x + 6 = <u>2x + 14</u>

ST = 7.2
RT = 4.04
m∠S = 34°
Solution:
Given ΔRST is a right triangle.
RS = 6, ∠T = 56°




1.206 × 6 = ST
7.236 = ST
ST = 7.2




0.674 × 6 = RT
4.044 = RT
RT = 4.04
To find the measure of angle S.
Sum of the interior angles of the triangle = 180°
m∠R + m∠S + m∠T = 180°
90° + m∠S + 56° = 180°
m∠S + 146° = 180°
m∠S = 180° – 146°
m∠S = 34°
