Answer:
168). C
169). C
170). C
Step-by-step explanation:
For the first angle, it is a right angle, so it measures 90 degrees.
x and 50 are complementary angles, meaning they add up to 90 degrees.
So, subtract 50 from 90 to get 40, which is equal to x.
45 and x are supplementary angles, meaning they add up to 180 degrees.
Subtract 45 from 180 to get 35 degrees, which is the measure of angle x.
All angles in a triangle add up to 180 degrees.
So, 70 + 56 = 126, 180 - 126 = 54.
Since the unknown angle is x - 5, 54 + 5 = 59, which the the measure of angle x - 5.
Answer:
And we know that the value for the west side is
So then if we solve for x from the last equation we got:
So then the east side is about long
Step-by-step explanation:
For this problem we know that the east side of Mrs. Hammond's ranch is 455 meters longer than the west side. Let's say that the east side is x and the west is y so we have this formula:
And we know that the value for the west side is
So then if we solve for x from the last equation we got:
So then the east side is about long
Answer:
1,203,650,000 mi³
Step-by-step explanation:
Volume of a sphere is given by V = (4/3)πr³
in this case diameter D, = 1320 mi
radius, r = D/2 = 1320 / 2 = 660 mi
volume V, = (4/3)(3.14) (660)³
= 1,203,649,920 mi³
= 1,203,650,000 mi³ (nearest thousand)
