• 20

An isosceles triangle has an angle that measures 40 degrees. 70 and 100 are other angles could be in that isosceles triangle

Solution:

Given that isosceles triangle has an angle that measures 40 degrees.

If a triangle is isosceles then it has 2 identical angles and the third different one.

Let the two identical angles be "a"

We know that sum of angles in a triangle is 180 degree

a + a+ 40 = 180

2a + 40 = 180

2a = 180-40

a = 70

Thus the two identical angles are 70 degree and 70 degree

Now let the identical two angles be "40" and the third angle be "a"

Now sum of angles = 180 degree

40 + 40 + a = 180

80 + a = 180

a = 100

Thus the third angle in this case is 100

70 and 100 are other angles could be in that isosceles triangle

answer is c

step-by-step explanation:

81/12=324/x

x=48

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
