answer it help me ...........answer this 3 questions plz

Answer:
Value of x is 10
Step-by-step explanation:
Let A be the angle for (8x-5)°
And B be the angle for(3x+45)°
Angle A = Angle B........( Alternate Angles)
therefore,
8x-5° = 3x+45°
8x-3x = 45 + 5
5x = 50
x=50
5
x=10

Answer:
5
10
10
Step-by-step explanation:
For the first,
ratio equals 7:4
that can be written as 7x and 4x with variable
now according to the the question on number has 15 more than the other ,
by looking at the above variables we can clearly see that 7x must be the one having 15 more than 4x , Since obviously 7x will be greater than 4x
so;
7x=4x+15
7x-4x=15 (shifting while changing signs)
3x=15
x=15/3
x=5 (solving that we get our answer)
(ii)by just looking at the picture we can identify that the two angles are equal alternate exterior angles therefore we can conclude that they are equal in measure.
8x-5=3x+45 (forming the equationand then shifting from left to right we can get our answer easily.)
8x-3x=45+5
5x=50
x=50/5
x=10
(iii) the number being x
the question says that 4times( x ) plus 5 equals the same as 35 plus x.
thus again forming the equation and shifting left to write we get our answer.
5+4x=x+35
4x-x=35-5
3x=30
x=30/3
x=10
Voila!
