Answer:
Step-by-step explanation:
So this is an isosceles triangle so the other angle must be x too.
So:
x+x+40 = 180
2x+40 = 180
2x = 140
x = 70
The rate of change of Pete's height from 3 to 5 years can be determined as,
Thus, the required rate of change from 3 to 5 years is 4 in/year.
Name them as vertices A,B,C , D and E in that order.
Answer:
y is equal to 2 and x is equal to 31 degrees.
Step-by-step explanation:
In order to find this, we must note that similar parts of congruent triangles are congruent. Since y is congruent to the part that is labeled 2, then it is an easy comparison.
x is a bit trickier. For this one, we must find the missing angle of the first triangle. To get that, we must subtract the given angle and the right angle from 180. This will give us x.
180 - 59 - 90 = x
31 = x
Answer:
Step-by-step explanation:
velocity of turtle = 5 feet / min
velocity of snail = - 11 feet / min
By using the formula of relative velcoity
the velocity of turtle with respect to snail is
V' = velocity of turtle - velocity of snail
V' = 5 - (- 11)
V' = 16 feet / min
