The ratio of the measures of two complementary angles is 7: 8 what is the measurement of the smaller angle?

42°

Step-by-step explanation: In this problem, we're given that the measures of two complementary angles are in the ratio 7 to 8 and we're asked to find the measure of the smaller angle.

Since our two angles are in the ratio 7 to 8, let's represent the angles as 7x and 8x. We will call 7x an angle and 8x its complement. Now, remember that if two angles are complementary, then the sum of their measures is 90 degrees. So we can set up the equation 7x + 8x = 90.

Simplifying on the left side, we have 15x = 90.

Dividing both sides by 15, we find that x = 6.

So the measure of our first angle, 7x, is 7(6) or 42°.

The measure of its complement, 8x, is 8(6) or 48°.

Finally, notice that if we add our two angles together, we have 42 + 48 which equals 90 so our answer checks. This means that the smaller angle is 42°. Image is provided below.

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
