Answer:
45 degrees
Step-by-step explanation:
Angle c is 90 degrees
and angle b and a have the same number of degrees
180-90=90
90 divided by 2 is
45
Answer:

Step-by-step explanation:

Given:
Big figure = 20 ft
Small figure = 7 ft
Take note: In finding the scale factor, we must make sure that the measurements of both figures are the same sides or line.
20 feet / 7 feet = 2.86 scale factor.
This means that the big figure is 2.86 times bigger than the small figure.
If the arrow had been pointed from the small figure to the big figure.
7 feet / 20 feet = 0.35 scale factor.
This means that the small figure is only 0.35 of the big figure.
Both are scale factors but in different perspectives.
SOH CAH TOA
This is the acronym for all trigonometric ratios.
Sin. = opposite/hypotenuse
Cos. = adjacent/ hypotenuse
Tan. = opposite/ adjacent.
In this picture the OPPOSITE leg and the HYPOTENUSE is given to us. With this information we can apply the "TOA" ratio.
Sin. R = opposite/hypotenuse
Sin. R = 3/4 or 0.75
Use a calculator or table to find 0.75 in the sin. column.
The final answer should be 49.
Sin. 49 = 0.7547
