Solution:
Given PRQ is a triangle.
ST is a line parallel to RQ.
<u>Triangle proportionality theorem,</u>
<em>If a line parallel to one side of a triangle intersects the other two sides, then it divides the two sides proportionally.</em>
Do cross multiplication, we get
Divide by 2x on both sides, we get
Do 50 multiplied by x = 8. Solve for x.
It would give you .16 which is 16%.
Answer:
x<y−1
Step-by-step explanation:
Hi there! For this question, you need to know the ratio of sine and cosine.
- sinA = opposite/hypotenuse
- cosA = adjacent/hypotenuse
Define A = angle
opposite and adjacent side changes only if we focus on another angle.
From the picture, if we focus on angle S, the opposite would be 36. But if we focus on angle R (flip to make RT as base), see that the opposite would be 14.
Answer
- sinS = 36/42 = 6/7
- sinR = 14/42 = 1/3
- cosS = 14/42 = 1/3
- cosR = 36/42 = 6/7
The bold one is simplest form while the non-bold is non-simplest.

Answer:
D.
Step-by-step explanation:
This is a perimeter question. All you have to do is add up all 4 sides together. In that case, it will be 2(3.5x - 7) + 2(x + 0.4). And we have our final answer!
