A. 3.25 or 3 1/4
B. 2
C. .25 or 1/4
D. -.75 or -3/4
E. -2.25 or -2 1/4
F. -3.75 or -3 3/4
I believe that A and D would be the correct answer. Because both are 30,60,90 triangles and would be congruent. The other 2 triangles only have 1 angle and their side measures are at two different places meaning they cannot be congruent.
w=7.5
Step-by-step explanation:
area of triangle is 6x5=30/2= 15 and then you divide 15 which 7.5
It’s wants 20 characters lol but the answer is b
Add the two angles and then subtract from 180* to find the missing angle
So,
145* + 15* = 160*
180* - 160* = 20*
Answer: x = 20*
