Answer:
x = 12
(2x + 1)° = 25°
(5x + 5)° = 65°
Step-by-step explanation:
By the property of a triangle,
Sum of all angles of a triangle is 180°
In the given right triangle,
(2x + 1)° + 90° + (5x + 5)°= 180°
7x + 96 = 180
7x = 180 - 96
x = 
x = 12
Angle (2x + 1)° = 2(12) + 1 = 25°
Angle (5x + 5)° = 5(12) + 5 = 65°
Therefore, all three angles of the right triangle are 25°, 90° and 65°.
Answer:
The required expression is: 
Option C is correct option.
Step-by-step explanation:
We need to find the equation that fits the description.
a) the expression is the quotient of two quantities
The quotient is expressed as 
where a is numerator and b is denominator
b) The numerator of the expression is product of 5 and the sum of x and y
Sum of x and y = x+y
Product of 5 and Sum of x and y = 5(x+y)
So, Numerator of the expression is 5(x+y)
c) The denominator is the product of negative 8 and x
Product of negative 8 and x = -8x
So, denominator of the expression is -8x
Now, The required expression is: 
Option C is correct option.
