PQ = RQ and <PQR = 60°
Triangle PRQ is equivalent triangle so <QPR = <QRP = <PQR = 60°
PS = RS, and <PSR = 90°, triangle PSR is a <span>right isosceles triangle
</span>So
a = <SRP = 45°
and
b = <QRP - <SRP
b = 60° - 45°
b = 15°
answer
a = 45°
b = 15°
Answer:
{-4, 3}
Step-by-step explanation:
To find "solutions," you must set this function equal to zero:
y = -7(x - 3)(x + 4) = 0
and then set each factor equal to 0 separately and solve each resulting equation for x:
x - 3 = 0 yields x = 3, and
x + 4 = 0 yields x = -4
So the pattern is multiplying each number by 4.
-3 × 4 = -12 (2nd term)
-12 × 4 = -48 (3rd term)
-48 × 4 = -192 (4th term)
-192 × 4 = -768 (5th term)
-768 × 4 = -3072 (6th term)
-3072 × 4 = -12288 (7th term)
-12288 × 4 = -49152 (8th term)
5 - 3x = -19
-3x = -24
Divide by -3
Solution: x = 8
