no, the angles in triangles have to add up to 180 deg. but this adds up to 190
Answer:
2 hours
Step-by-step explanation:
using the relationship
distance = speed × time, then
time = 
= 
= 2 hours
Answer:
x^16
Step-by-step explanation:
We know that a^b * a^c = a^ (b+c)
x ^7 * x^9
x^(7+9)
x^16
<h3>
Answer: x = 35 (choice D)</h3>
====================================================
Work Shown:
secant angle = (far arc - near arc)/2
angle BGC = (arc BC - arc AD)/2
40 = (115 - x)/2
2*40 = 115-x
80 = 115-x
115-x = 80
-x = 80-115
-x = -35
x = 35
For more information, you can search out "secant angles" and it should go over how the formula is set up and why it works.
