Because the 2 sides of the triangle are the same, they are both 21, the two bottom angles would also be the same.

The 3 inside angles of a triangle must equal 180 degrees.

The top angle is given as 38, so the remaining two angles must equal 180 - 38 = 142 degrees.

Since the 2 bottom angles would be the same, divide 142 by 2 to get x.

X = 142 / 2 = 71 degrees.

Find the value of n .<br> 6/n = 24/28<br> y = ___.

il63 [147K]

Answer:

$n=7$

Step-by-step explanation:

Cross multiply, isolate the variable, and divide by the coefficient to solve.

$\frac{6}{n}=\frac{24}{28} \\ \\ 24n=168 \\ \\ n=7$

Plug back in to check.

$\frac{6}{7}=0.857142857 \\ \\ \frac{24}{28} =0.857142857$
