Answer:
315
Step-by-step explanation:
Answer:
A. <BED and <DEA, <AEC and <BEC
Step-by-step explanation:
Supplementary angles add up to give 180°.
m<BED = 90°
m<DEA = 90°
m<BED + m<DEA = 180°
Therefore, <BED and <DEA are supplementary.
m<AEC = 90°
m<BEC = 90°
m<AEC + m<BEC = 180°
Therefore, <AEC and <BEC are supplementary.
Answer:
4y=9x
Step-by-step explanation:
Answer:
x = 1/2
Step-by-step explanation:
9^x -1 = 2
Add 1 to each side
9^x = 2+1
9^x = 3
Rewriting 9 as 3^2
3^2x = 3
3^2x = 3^1
The bases are the same so the exponents must be the same
2x =1
2x/2 =1/2
x = 1/2
Replace X with 3 and simplify. The answer you would get is 11.
