Answer:
x=7
Step-by-step explanation:
Step 1: Subtract 4x from both sides.
x+30−4x=4x+9−4x
−3x+30=9
Step 2: Subtract 30 from both sides.
−3x+30−30=9−30
−3x=−21
Step 3: Divide both sides by -3.
−3x
−3
=
−21
−3
<u><em>The sides of a rhombus are all congruent (the same length.)</em></u>
Answer:
x = 2.
y = 6.
Step-by-step explanation:
Consider the triangle on the left.
Because there are 2 equal angles at the vertex on the bottom right:
3/9 = x/(8 - x)
1/3 = x / (8 - x)
3x = 8 - x
4x = 8
x = 2 (answer).
Similarly, for the second triangle:
3/y = 2/4
3/y = 1/2
y = 6
(answer).
