PLEASEE HELPP MEEE WITH QUESTION 1 AND 2

Step-by-step explanation:

Question 1:

All triangles have a sum of 180°.

180 - (56 + 39)

180 - 95 = 85

So, now that you know the measurement of the third angle of the triangle, you can find the missing exterior angle. Exterior angles and interior angles that are side-by-side are supplementary angles meaning that have a sum of 180°. So, you would subtract 85 from 180 which is 95.

So, the measurement of the missing angle is 95°.

Question 2:

All triangles have a sum of 180°.

we already know the angle of ∠1 and since the triangle is an isosceles triangle, then both of the base angles have a measurement of 67°. Now, we find the value of x.

180 - (67 + 67)

180 - 134 = 46

3x - 14 = 46

3x = 60

x = 20

So, the value of x is 20.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
