I’m almost positive it’s C
Answer:
55 degrees.
Step-by-step explanation:
ok so first off we know altogether the angles of a triangle have to equal 180 degrees total we have one thats 80 so the other two together must be 100 given that information we can make the equation 7x+6+3+6x=100 we simplify to get 13x+9=100 after moving it around you get 13x=91 solve the equation by dividing both sides by 13 to get x=7, but we are not done we have to solve for angle A by inputting the X so we get angle A=55 degrees
The value of Amanda's investment will be given by:
A=P(1+r)^n
where:
Principle, P=$1000
rate,r=3.5%
time,n=4+9/12=4 3/4=4.75 years
thus
A=1000(1+3.5/100)^4.75
A=$1177.52
The answer is obvious its the answer to anything else 42<span />
x = 160
Steps:
x+20=180
Subtract 20 from both sides
x+20-20=180-20
20 is crossed out
180-20 = 160
x = 160
To check plug in 160 for x
160 + 20 = 180
180 = 180
Hope this helps you! (:
