Answer:
x = 11
Step-by-step explanation:
Since we are given triangle PQR is similar to triangle PTU, we can write a proportion to connect the side lengths:
PQ / PT = QR / TU = PR / PU
We don't really care about QR and TU because the are irrelevant to the problem, so we can remove them:
PQ / PT = PR / PU
Now, we can substitute the values given by the diagram:
70 / 30 = 49 / (x + 10)
We can cross multiply,
70(x + 10) = 30 * 49
And divide by 70 on both sides(too lazy to multiply :P)
x + 10 = 3 * 7
x + 10 = 21
x = 11
Answer:
<em>y=</em><em>1</em><em>/</em><em>3</em><em> </em><em>would </em><em>be </em><em>the </em><em>correct</em><em> </em><em>answer</em><em> </em><em>as </em><em>long </em><em>as </em><em>the </em><em>x </em><em>is </em><em>not </em><em>only </em><em>attached</em><em> to</em><em> the</em><em> </em><em>three,</em><em> </em><em>but </em><em>1</em><em>/</em><em>3</em><em> </em><em>as </em><em>a </em><em>whole</em><em>.</em><em> </em><em>I </em><em>hope</em><em> </em><em>this </em><em>helps!</em>
Answer:
13212
Step-by-step explanation:
Answer:

Step-by-step explanation:
Area of triangle = 0.5 × Base × Height
→ Substitute in the values
200 = 0.5 × 5x × 5x
→ Simplify
200 = 12.5x²
→ Divide both sides by 12.5
16 = x²
→ Square root both sides
4 = x ∴ x = 4
