Answer:
x = 8; y = 5
Step-by-step explanation:
x + y = 13
x - y = 3
8 + 5 = 13
8 - 5 = 3
Answer:
volume of the triangular pyramid=1/3×base×height
=1/3×(1/2×6×5)×10
=1/3×15×10
=50 yd³
Answer:
x = 5
m∡B = 66°
Step-by-step explanation:
these two angles are same-side interior angles, which are supplementary
8x + 74 + 2x + 56 = 180
10x + 130 = 180
10x = 50
x = 5
m∡B = 2(5) + 56 = 66°
