Triangle PQR is given to be a right triangle, so the Pythagorean theorem can be used to determine that RQ² + PR² = PQ².
<h3>What is Pythagorean theorem?</h3>
Pythagorean theorem is a mathematical expression in Euclidean geometry that can be used to solve for any of the three (3) side lengths of a right triangle.
Mathematically, Pythagorean's theorem is given by this formula:
x² + y² = z²
Triangle PQR is given to be a right triangle, so the Pythagorean theorem can be used to determine that RQ² + PR² = PQ². It is given that x² + y² = z² in triangle ABC, so z² = PQ² or AB = PQ.
The above information shows that the triangles are congruent because their three (3) sides are congruent. Therefore, to show that triangle PQR is a right triangle, we can use corresponding parts of the congruent triangles to show that PQ = AB, PR = AC and QR = BC.

Answer:
Each guest got 3. (if he doesn't have any for himself).
Step-by-step explanation:
if each guest is x
30=10x
divide by 10
x=3
hope this helps and if you want please consider giving me brainliest! :)
<h3>Since they are vertically opposite angles then we can set the two angles equal to each other.</h3>
<h3>Subtract 30 from both sides</h3>
<h3>Divide both sides by 8</h3>
Step-by-step explanation:
3^2 + 3^2 =5^2
9 +9 =25
18 =25
False 18 is not equal to 25.
First do 28/2 to find min per lawn
It's 14
Then do 14 x 5 to find out how many minutes it take him to mow 5 lawns
It's 70
FYI 70 min is 1 hr n 10 min
