Answer:

K = 39.5

Step-by-step explanation:

We assume that when all the angles are added together they are equal to 360°, hence:

k + 3k + 87 + 115 = 360 \\  \\ 4k + 202 = 360 \\ 4k = 360 - 202 \\  4k = 158 \\

\frac{4k}{4} =  \frac{158}{4}  \\  \\  k = 39.5

Andrews [41]

Answer:

The area of ΔABC= 6.667 square units

Step-by-step explanation:

ΔABC is similar to ΔMNO.

The scale factor from ΔMNO to ΔABC is 3∕2

the area of ΔMNO is 10 square units,

The area of ΔABC/the area of ΔMNO

= 2/3

The area of ΔABC/10= 2/3

The area of ΔABC= 2/3 * 10

The area of ΔABC= 20/3

The area of ΔABC= 6 2/3

The area of ΔABC= 6.667 square units
