Answer:
4). A) .20 , .194 B) the Cost-Co price is better 5) A) 476.991 , 479.99
B) 10% is better
Step-by-step explanation:
The angle x and 70 are alternate interior so that means they measure the same.
In an isoceles triangle the base angles are the same so that means that both the x angles are 70.
Now we can subtract their sum by 180 to find the measure of angle 1.
180 - (70 + 70) = 40
So the measure of angle 1 is 40.

i dont know
Step-by-step explanation:
The answer is 1 3/8.
2 3/4 / 2(unsimplifying is next)
11/4 / 2
11/8 (simplifying is next)
1 3/8
Initially started 20 feet from the ground .
Went uphill 83 feet.
So: 20 + 83 = 103. The coaster is 103 ft above at this point.
Went down 42 feet
So: 103 - 42 = 61.
Went up 128 feet
So: 61 + 128 = 189
Finally, went down 90 feet
So: 189 - 90 = 99
99 ft above ground.
