H^2=13^2-5^2
h^2=169-25
h^2=144
h=V144
h=12
A=b*h/2=10*h/2
A=10*12/2=120/2=60 cm^2
Answer:
the angle in ascending order is 24°, 36° and 120°
Step-by-step explanation:
The largest angle of a triangle is 5 times as large as the smallest angle
The third angle is 12 degrees more than the smallest angle.
let the smallest angle be x
the largest angle is 5x
the third angle is (12+x)
the sum of angles in a triangle is 180°
x + 5x + (12+x) = 180
x+5x+ 12+x = 180
7x+12 = 180
7x = 180 -12= 168
x = 168/7 = 24°
the smallest angle is 24°
the largest angle is 5x= 5 x 24 = 120°
the third angle is 12 +x = 12+24 = 36°
Answer:
I'm a little rusty on this type of math, but I'll answer to the best of my ability.
Step-by-step explanation:
They will be similar. I have no idea on the scale factor, and the angle pair is DAC = EAB
I'm sorry I couldn't help more.
