Step-by-step explanation:

Question 6 is an easy Question.

Here is how it is done.

Supplementary angles are two angles whose sum is 180°

let x and y be the two angles

and angle y > angle x

According to Question, The larger angle (y) is 36° more than the smaller angle (x)

Now putting the statement into an equation, we get,

y = x + 36

Now we know,

x + y = 180°

substitute y with the value we got

x + x + 36 = 180

2x + 36 = 180

2x = 144

x = 72°

now substitute it in the equation, y = x + 36

y = 72 + 36

y = 108°

As for 7th Question,

Base Angles are the two angles which have a common base.

80° is the angle given that's different from the two.

In an Isosceles triangle, two sides are equal and so are two sides.

Apply Angle Sum Property of a Traingle

A + B + C = 180°

80 + 2B = 180° [B = C, as earlier mentioned]

2B = 100°

B = 50°

Hope this helps ☺️

Answer:

7. let the base angles b x° each ( since base angles are equal)

we know that

sum of all angles of a ∆ = 180 °

=> x + x + 80 = 180

=> 2x = 180 - 80

=> x = 100/2 = 50°

so,

base angles are 50° each
