Im not good at this, thought Ive done Geometry, But for the first one (180-70) which should be 110, and for the second one I would say 55.
Answer:
Step-by-step explanation:
volume=area *lenght
for area=2area of triangle +area of rectangle
a=2root(s(s-a)(s-b)(s-c))+7*4 {s is (a+b+c)/2 so s=(3+4+5)/2 finding 5 by pythagoras theorem so s=6}
a=2root(6(6-2)(6-4)(6-5))+28
a=2root48+28=41.85inch^2
now volume=41.86*5 given in fig height is 5
so v=209 inch^3
Answer:
The measure of the arc DAC is 240°
Step-by-step explanation:
we know that
The semi-inscribed angle is half that of the arc it comprises.
so
m∠RDC=(1/2)[arc DAC]
we have
m∠RDC=120°
substitute
120°=(1/2)[arc DAC]
240°=[arc DAC]
Rewrite
arc DAC=240°
Answer:
d = -2
Step-by-step explanation:
2d - 5d = -3d
10 - 4 = 6
-3d = 6
d = -2
