For the first one the answer is 17
And for the second one its 5.5
Answer:
Step-by-step explanation:
By the Triangle Proportionality Theorem:
By cross-multiplication:
Distribute:
Subtract 12x from both sides:
Hence:
So you are multiplying the fractions together. You do not need a common denominator. You multiply the numerators together and the denominators to get your new fraction.
1x4=4
4x7=28
4/28
This fraction can now be simplified by dividing the numerator and denominator by 4
4/28x4/4
1/7
Answer:

Answer:
Step-by-step explanation:
Given
Required
Find 
implies that is between 0 and 180 degrees
Take arcsin of both sides
This gives:
Convert to degrees
We have:
or 
To get other values of
We use:
Substitute:
<em>This means that there are no other values of </em><em> in the given range</em>
