Answer:
(c) 52.0
Step-by-step explanation:
The angle whose cosine is 8/13 is found using the inverse cosine function:
y° = arccos(8/13) ≈ 52.0°
y ≈ 52.0
__
The calculator button to compute this value is probably labeled cos⁻¹. You may need to access the function using a <em>Shift</em> or <em>2nd</em> key. The calculator must be set to degrees mode to prevent the answer from appearing in radians or grads. If you use a spreadsheet, your formula may look like ...
=DEGREES(ARCCOS(8/13))
we know that
<u>The Division Property of Equality</u> states that if you divide both sides of an equation by the same number, both sides of the equation will remain equal
so
in this problem we have

Solve for x
Using the Division Property of Equality, Divide by
both sides


therefore
<u>the answer is the option</u>
c. 2y/5 ( 2y over 5 )
Answer:
m=-32
Step-by-step explanation:
-2=m/16
-2×16=m
-32=m
m=-32
