Answer:
2^1×2^3
2^8×2^−5
2^1×2^2
Step-by-step explanation:
8.6 first number after the decimal is the tenths place then the second number after the decimal is the hundredths
The angle of depression equals 32.
A way that you can solve this is by finding angle c. Angle C would be the same as the angle of depression because of alternate angles being congruent.
So you do the triangle angle sum theorem.
58+90+x=180
Simplify
148 +x=180
Subtract 148 from both sides
x=32
So Since angle c equals to 32 degrees, then the angle of depression is also 32 degrees.
