Help find value of X please!

Explanation:

The mixed number 7 & 1/4 converts to the decimal form 7.25, since 1/4 = 0.25

The ratio 1:7.25 means that we'll multiply the smaller triangle's sides by the scale factor 7.25 to get the larger corresponding side

Meaning that the value of x is 3*7.25 = 21.75

This converts to the mixed number 21 & 3/4

D

Step-by-step explanation:

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.

the correct answers i think are b. and d.

give me brainliest if it is correct!
