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
