From the diagram, all three angles are 90° (Diagonals of a Rhombus)
Angle 1 = 9x = 90
⇒ 9x = 90
x = 90/9
x = 10
Angle 2 = y + x = 90
⇒ y + x = 90
since x = 10,
y + 10 = 90
y = 90 - 10
y = 80
Angle 3 = 15 z = 90
⇒ 15z = 90
z = 90/15
z = 6
Answer is Option C
<span>C. x = 10, y = 80, z = 6</span>
D<span>here, we go by the same exact principle, but the terms are not a,b,c.

Answer:
y=6
Step-by-step explanation:
all you do is add 4 and 2
The answer must be
since the triangular pyramid has 4 faces and each has an area of 30
we should multiply that by 4 , so :
