The length of PR is 4.4 units.
Explanation:
It is given that the length of the hypotenuse is 10 units.
Also, the angle of R is 64°
To find the length of PR, we shall use the cosine formula,
Here, 
, adj = PR and hyp = 10
Substituting these values in the formula, we get,
Multiplying both sides by 10, we get,
Substituting the value for cos 64, we get,
Multiplying, we have,
Rounding off, we get,
Thus, the length of PR is 4.4 units.

Step-by-step explanation:
isosceles right
because A light ray incident at 90° at the first face emerges at the same angle. The diagram shows five isosceles right-angled prisms. A light ray incident at 90° at the first face emerges at the same angle with the normal from the last face.
Answer:
c
Step-by-step explanation:
you would put -142 in the x place
-0.2(-142+223)
-0.2(81)=-16.2
Answer:
Step-by-step explanation:
If apricots is x, and each apricot weighs 5 grams, then the expression for that is 5x; if each cherry, y, weighs 2 grams, then the expression for that is 2y. If the mix Roy wants to make needs AT LEAST 230 grams of fruit, then
5x + 2y ≥ 230 where the inequality sign "greater than or equal to" satisfies the expression "at least".
