In ΔRST, the measure of ∠T=90°, the measure of ∠S=76°, and ST = 63 feet. Find the length of RS to the nearest tenth of a foot.

The length of ST to the nearest tenth of a foot is 5.2 ft

Step-by-step explanation:

OK lets hope to it

∡T = 90°

∡R = 64°

RS = 5.8 ft

To answer the question, we have apply sine rule as follows;

Therefore, for triangle RST, we will have;

Therefore;

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

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
