The angle measures tell you the triangles are similar, so corresponding sides will have the same ratio.
GX/BX = UH/NH
GX = BX·UH/NH
GX = 7·18/(3√11)
GX = (42/11)√11
GB/BX = UN/NH
GB = BX·UN/NH
GB = 7·15/(3√11)
GB = (35/11)√11
Answer:
C
Step-by-step explanation:

H = 4(x + 3y) + 2
H = 4x + 12y + 2
H - 12y - 2 = 4x
(H - 12y - 2) / 4 = x or 1/4H - 3y - 1/2 = x
9+(-9)=0 you are showing the opposite sign of the number that added together would give you the sum of zero.
Interpret the exponent in the formula. S to the third power means to use s as a factor 3 times.
V = S to the third power = S x S x S
Find the volume of the first cube.
Substitute 4 for s.
V = 4 x 4 x 4 = 64
Find the volume of the second cube.
Substitute 7 for s.
V = 7 x 7 x 7 = 343
Tamara's first cube has a volume of 64 cubic centimeters, and her second cube has a volume of 343 cubic centimeters
