Ilya [14]3 years ago

Answer:

n=31.5

Step-by-step explanation:

The given question is:

\frac{14}{n+7}=\frac{10}{n-4}

Cross multiply to get:

14(n-4)=10(n+7)

Expand the parenthesis:

14n-56=10n+70

Group similar terms:

14n-10n=70+56

Combine the like terms

4n=126

Divide both sides by 4

n=\frac{126}{4}

n=31.5

What’s the measure of the missing angles?
Ymorist [56]

Answer:

Angle 1 equals 90 degrees. Angle 2 equals 38 degrees.

Step-by-step explanation:

Angle 1 is at the cross of two perpendicular lines, making it 90 degrees. Angle 2 can be found by making the two equal side lengths and the middle line into one triangle. This means that two of the angles are 52 degrees. This leaves 76 degrees to be split in the triangle. The middle line cuts the angle in half, making it 38 degrees
