Find the following angle measures. mEAD = ° mCAB = °

sergejj [24]

Part 1) Find m∠EAD

we know that

m∠EAD+m∠DAF+m∠BAF= $180\°$ ----> by supplementary angles

solve for m∠EAD

m∠EAD= $180\°$ -(m∠DAF+m∠BAF)

in this problem we have

m∠DAF= $90\°$

m∠BAF= $61\°$

substitute in the formula above

m∠EAD= $180\°-90\°-61\°=29\°$

therefore

the answer part 1) is

m∠EAD= $29\°$

Part 2) Find m∠CAB

we know that

m∠CAB+m∠BAF= $180\°$ --------> by supplementary angles

solve for m∠CAB

m∠CAB= $180\°$ -m∠BAF

in this problem we have

m∠BAF= $61\°$

substitute in the formula above

m∠CAB= $180\°-61\°=119\°$

therefore

the answer part 2) is

m∠CAB= $119\°$

elaine's mother is now 38 years old. seven years from now she will be five times as old as elaine will be then. write and solve

vfiekz [6]

In seven years her mother will be 38 +7 = 45 years old.

She will be 5 times as old, so divide 45 by 5: 45/5 = 9. Elaine will be 9 years old then, so she is 9-7 = 2 years old now.

Answer:

c= $\sqrt{52}$

Step-by-step explanation:

a=height=6

b=length=4

using pythagorean theorem

a^2+b^2=c^2

36+16=c^2

c= $\sqrt{36+16}$

c= $\sqrt{52}$
