A*5+b*2=145
a +b =50 | * -2
5a +2b=145
-2a -2b = -100
----------------------
5a-2a = 145-100
3a= 45
a=45:3
a=15 questions are worth 5 p
b=50-15=35 questions worth 2 p
Answer:
Ruben ate 6 pieces out of 8.
Step-by-step explanation:
We will understand 3/4 first. If we divide a pie into 4 pieces then Ruben ate 3 pieces of pie.

<u>Trigonometric Ratios
</u>
The ratios of the sides of a right triangle are called trigonometric ratios.
The longest side of the triangle is called the hypotenuse and the other two sides are the legs.
Selecting any of the acute angles as a reference, it has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides.
Selecting the angle of 18°:
Tangent Ratio:


Solving for X:

Operating:

X = 29.9
