In ΔRST, r = 850 cm, s = 250 cm and t=940 cm. Find the measure of ∠S to the nearest 10th of a degree

5.2

Step-by-step explanation:

∡T = 90°

∡R = 64°

RS = 5.8 ft

To answer the question, we have use the sine rule

So, for triangle RST, we will have;

Therefore, the length of ST to the nearest tenth of a foot = 5.2 ft.

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign
