Answer:
i think it A
Step-by-step explanation:
Given:
The sum of two angles 5x and 50 degrees equals 90 degrees.
To find: The value of x
Explanation:
Since the sum of two given angles equals 90 degrees.
So, we can write it as,

Solving for x we get,

Thus, the value of x is 8.
Final answer: The value of x is 8.
Answer:
x is equal to 15.
Step-by-step explanation:
In order to solve this, we need to set it up as a proportion.
6/8 = x/20
Now that we have the proportion, we need to cross multiply to solve.
6*20 = 8*x
120 = 8x
15 = x

Answer:
D. 102.6 in²
Step-by-step explanation:
The area of the square is 9 in² (3 × 3 = 9)
The area of the rectangle is 30 in² (3 × 10 = 30)
The area of the circle is 63.585 (a = πr², a = 3.14 × 4.5² - remember that the radius of a circle is half of the diameter)
Now, we can add these numbers together. 9 + 30 + 63.585 is 102.585 in² which is 102.6 in² rounded to 1 decimal place.
Hope this helps!
