Find the unknown angle mesure

1=65° and 5=43

Step-by-step explanation:

Question 1:

Angles on a straight line always add up to 180°.

So to find the angle of x on the first question you have to do 180-115=65°

You would have to use this method for questions 2, 3 and 4 as well.

Question 5:

Right angles always add up to 90° so to work out what x is you would have to do 90-47=43

You would have to use this method for questions 6, 7 and 8.

Hope this helps :)

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25

b.my answer is b.
