Step-by-step explanation:
Here we will, Provide index power 5 on both the sides, so that we can cancel out the 5th power root in the L.H.S
so we get as,
==> x+7 = (-2)^5
==> x+7 = -32
==> x = -32-7
==> x = -39
hence, x = -39
Option A.) is correct.
Answer:
The angle
at which the sun is hitting the ground is:

Step-by-step explanation:
You can use right angle trigonometry to solve this, since the man (6 ft tall) and the shadow on the ground (3.5 ft long) form a right angle triangle as shown on the attached image.
The use the tangent function to find the angle that the sun's rays make with the ground:

Answer:
The slope of line e is -5/6
Step-by-step explanation:
The slope of line d that passes through (3,4) and (8,10) is 6/5. To find the slope of a perpendicular line you simply change the sign and flip the numerator and denominator.
It equals 72. If you have a problem like this again first start with the brackets, and the parentheses inside the brackets (if there is any). Then move onto the others outside the brackets like other parentheses (if there is any)
