Answer: c
Step-by-step explanation:
105 x 4 = 420
63 x 7 = 441
420 + 441 = 861
Answer:
V=Bh/3
Explanation:
B=3V/h
1) Multiply h on both sides.
Bh=3v
2) Divide both sides by 3
Bh/3=V
Answer: (3,6)
Rewrite in vertex form and use this form to find the vertex (h,k)
A) 180-125 =55
B) both bottom angles are 55 and the triangle's angles should add up to 180, so 55 + 55 + x = 180. X = 70
C) CAE and CBD are equal so the bottom angle (that was calculated in A) will be the base acute angle —>55
