Question

find the ans plz fast its maths

Answer 1

a) In Q 15 part 1,

Angle PRS = 115 degree

Therefore Angle PRQ = 180 - 115 = 65 degree

And Angle Q = 180 - ( 65 + 45)

=> 180 - 110

=> 70 degree (Answer)

b)  In Q 16,

3/5 / 6/10 = 3/5 * 10/6 = 2/2 = 1

c) If x = 2

Then 2x + 1 = 5

=> 2*2 + 1 =5

=> 4 + 1 = 5

=> 5 = 5

Hence x = 2 (Proved)

Pls markk brainliest :D

Answer 2

Step-by-step explanation:

The first question is simple. We know that 1 line is equal to 180 degrees. We also know that one triangle is equal to 180 degrees adding up all angles. One of the angles is, 115, so we subtract 115 from 180. 65 is what we're left with. We know have 2 angles. 65 + 45 = 110. 180-110= 70.

3/5 / 6/10 is the same as 3/5 x 6/10. This is much easier. 3 x 10 is 30. 5x 6 is 30. 30/30 is 1. So the answer is 1.

If x = 2 then 2x + 1 = 5. Now we do 2*2 + 1 =5. Now 4 + 1 = 5 and 5 = 5. Therefore x=2
