First, turn it into a multiplication problem by multiplying by the reciprocal of the divisor. Then, you can cancel common factors in the numerator and denominator to make things easier to work with. Finally, multiply<span> to get your final answer!</span>
Area of a triangle = 1/2 x base x height
using the given information: area = 40 and base = 20
you now have 40 = 1/2 x 20 x height
divide both sides by 1/2
80 = 20 x height
divide both sides by 20
height = 80 / 20
height = 4 in.
Answer:
7. 5/6 8. 3/12
Step-by-step explanation:
You can revise: the sum of the two adjacent angles is 180°
and the sum of the measurements of the three corners in a triangle is also 180°
<1= 180°-57°=123°
As <2=52°, so we have <3= 180°-(28°+71°+52°)= 180°-151°=29°
have fun
-18x-17=-53 /add 17 to both sides
-18x-17+17=-53+17
-18x=-36
x=(-36)/(-18)
x=2
