Answer:
y = 4 x = 8
Step-by-step explanation:
x goes first y last (X,Y)
All the length, width and height doubled
Answer:
Angle D is equal to 80.
Step-by-step explanation:
We know that the sides are congruent and that angle ACB is congruent to angle ECD by the vertical angles theorem.
Triangles' angles always add up to 180.
180 - 70 - 30 = 80
angle D is equal to 80.
Let's solve your equation step-by-step.<span><span><span><span>√x</span>+10</span>−9</span>=<span>−7
</span></span><span><span><span>√x</span>+1</span>=<span>−7
</span></span>Step 1: Add -1 to both sides.
<span><span><span><span>√x</span>+1</span>+<span>−1</span></span>=<span><span>−7</span>+<span>−1
</span></span></span><span><span>√x</span>=<span>−8
</span></span>Step 2: Solve Square Root.
<span><span>√x</span>=<span>−8
</span></span><span>x=<span><span>(<span>−8</span>)</span>2</span></span>(Square both sides)
<span>x=64
