Answer:
x = 15
Step-by-step explanation:
according to Altitude Theorem, we can set up this proportion:
9/RT = RT/16
RT² = 9(16)
RT² = 144
RT = ![\sqrt{144}](https://tex.z-dn.net/?f=%5Csqrt%7B144%7D)
RT = 12
In right triangle STR, we can find 'x' by using the Pythagorean Theorem:
9² + 12² = x²
81 + 144 = x²
225 = x²
x = √225 = 15
(3s^13)(9s^-5) is simply a matter of multiplication.
First, multiply the coefficients, or the numbers in front of the s. In this case, 3s x 9s = 27s.
When multiplying exponents, you simply add them, so the next step is 13-5 or 8. Therefore your answer is 27s^8
Answer:
40°
Step-by-step explanation:
Because triangle QSR is isosceles ∠SQR=∠SRQ=35°. The sum of the angles in a triangle is 180°, so ∠QSR=180°-35°-35°=110°. The measure of a straight line is 180°, so ∠PSQ=180°-110°=70°. Because triangle PSQ is also isosceles ∠PSQ=∠PQS=70°. Then, ∠QPS=180°-70°-70°=40°.
