Answer:
x = 12, y = 4
Step-by-step explanation:
For the triangles to be congruent by HL , then
x = y + 8 → (1)
4y = x + 4 → (2)
Substitute x = y + 8 into (2)
4y = y + 8 + 4
4y = y + 12 ( subtract y from both sides )
3y = 12 ( divide both sides by 3 )
y = 4
Substitute y = 4 into (1)
x = 4 + 8 = 12
Step-by-step explanation:
<em>2 . 14 x − 42 . 9 for x = 22 . 4 .</em>
- 2.14(22.4) = 47.936
- 47.936-42.9 = 5.036
your answer is 5.036

Step-by-step explanation:
<u>Step 1: Define</u>
We have a right triangle triangle. We can use trig to find the missing length.
<u>Step 2: Identify Variables</u>
<em>POV from the angle measure</em>
Angle = 64°
Opposite = 13
Adjacent = <em>x</em>
<em />
<u>Step 3: Solve for </u><em><u>x</u></em>
- Substitute: tan64° = 13/x
- Multiply <em>x </em>on both sides: xtan64° = 13
- Isolate <em>x</em>: x = 13/tan64°
- Evaluate: x = 6.34052
