4 quarters and a dime and a nikcle
Sent a picture of the solution to the problem (s). I took a guess at what it asked.
Answer:
b = 7.56 cm
Step-by-step explanation:
Sum of the angles in a triangle = 180
so m∠A = 180 - 75 - 36 = 69 ;
use the law of sines:
(sin A) / a = (sin B) / b = (sin C) / C.
Now plug in ∠A = 69 into formula (sin A) / a = (sin B) / b and solve for b:
(sin 69) / 12 = (sin 36) / b
cross multiply:
b sin 69 = 12 sin 36 divide each side by sin 69
b = {12 sin 36} / sin 69
b = (12 sin 36) / sin 69 = 7.555........
b = 7.56
Answer: <u><em>Problem 1</em></u>
SA = 430.0
Step-by-step explanation:
13*11=143 divided by 2 is 71.5 (front face of the figure)
13*11=143 divided by 2 is 71.5 (backk face of the figure)
13*7=91 (left side rectangle)
17*7=119 (right side face rectangle)
11*7=77 (base)
Add all together 71.5+71.5+91+119+77=430.0
<u><em>Problem 2</em></u>
10*9=90 divided by 2 = 45 (front face triangle)
10*9=90 divided by 2 = 45 (back face triangle)
10*9=90 (right side rectangle face)
10*13.5=135 (left back side rectangle face)
10*10=100 (base)
Add everything together
45+45+90+135+100=415.0
Hope this helps!
Answer:
Measure of <N = 60°
(angles in an equilateral triangle are all equall 60°)
the measure of ∠M= 60°
(angles in an equilateral triangle are all equall 60°)
Step-by-step explanation:
Sum of angles in a triangle is equall to 180....
And in equilateral triangle of all sides equall...all angles are equal to 60° because all sides are equal.
So <m= <n=<o=60°
