Answer:
11°
Step-by-step explanation:
Here in the figure , angle(BAC) = angle(QSR) = 45°
also, angle(ABC) = angle(SQR) = 80°.
In triangle SQR,
angle(QSR) + angle(SQR) + angle(SRQ) = 180°
=> angle(SRQ) = 180 - ( 45 + 80 )
= 180 - 125
= 55°
But angle(SRQ) = 5x ( its given in question )
So,
5x = 55°
=> x = 11°
Answer:
1,542,682 cm^3.
Step-by-step explanation:
The scale factor = √169:√289
= 13:17
So the Volume ratio is 13^3:17^3
So the volume of the larger solid is 689,858 * (17^3/13^3)
= 1,542,682 cm^3.
Answer:given below
Step-by-step explanation:
sqrt x^2 +81= x + 10
x^2 + 81 = (x+10)^2
x^2 + 81 = x^2 + 20x + 100
so answer is:
x^2 + 81 = x^2 +20x + 100

Answer: D
Because there is a dashed line, that means there has to be an inequality statement, C is the only one with one and the statement is false.
