Answer:
8
Step-by-step explanation:
Two angles are complementary when their sum is equal to 90°.
So, ( 2x + 39 ) + ( 7x - 21 ) = 90°
9x + 18° = 90°
x = 8°
Putting value of x in the angles given :
( 2x + 39 )° = 2(8°) + 39° = 55°.
( 7x - 21 )° = 7(8°) - 21° = 35°.
Therefore, the angles are 55° and 35°.
Hence, this is the required solution.
Answer will be option 2nd.
S(-4,7), T(-7,0), U(-1,0)
Answer:
Step-by-step explanation:
You multiply it by itself 4 times, therefore being 18 to the power of 4
The two correct answers are A and E. You can immediately eliminate C and E because to bring over something that is multiplied you have to divide (fraction). And B isn't the answer because to isolate s you divide by πr which would bring <span>πr to the denominator, not the numerator.
