The missing angle is 25. A triangle is always equal to 180° so you would subtract your know angles from 180 to find the missing angle
75+80+x=180 would be the equation

8090 [49]
The diameter can be obtained by the formula A = pi*r^2

First, multiply 0.50 * 100 to obtain the area of the ball, then simplify and solve for the radius. Doubling the radius would yield the diameter. This is shown below:

Area of the ball = 0.50 * 100 = 50 in^2
<span>A = pi*r^2
</span>50 = (3.14)*r^2
r = 3.99 = approx. 4
diameter = 2r
Diameter = 8 inches.

Among the choices, the correct answer is C. 8.0 in.

Alice planted some corn in the back yard and measures it’s height regularly. The last time she checked, the stalks were 60 inche
sdas [7]

Answer:

The percent of increase in height of the stalks is 20%.

Step-by-step explanation:

The general formula for a percent increase is as follows:  (Original Amount - New Amount/Original Amount) x 100.  The original height of the stalks was 60 inches tall.  The new height of the stalks is 72 inches.  In the numerator of our fraction, we take 72-60 to get 12.  Our denominator is the original amount, or 60.  This gives us an overall fraction of 12/60, which when we divide gives us 0.2.  Once we multiply our decimal by 100, we get an overall percent increase of 20%.
