Answer
A = 35 degeres and B = - 12
Step-by-step explanation:
The answer is 1x because -10 divided by -10 is 1 so add the x to get 1x
Answer:
h=5in
Step-by-step explanation:
The following areas are equal:
1. Front and Back.
2. Left and right.
3. Top and Bottom.
Therefore, we calculate 3 areas and
multiply each by 2 to get the 6 areas:
As=2(3*h) + 2(10*h) + 2(10*3)=1901n^2.
6h + 20h + 60 = 190,
26h = 190 - 60 = 130,
h = 5in.
60 degrees
Right angles add up to 90 so 90-30=60
Answer:
Step-by-step explanation:
take 60 degree as reference angle
using cos rule
cos 60=adjacent/hypotenuse
1/2=80/x(do cross multiplication)
80*2=x
160=x
