Answer:

C.

Step-by-step explanation:

<em>The measure of the angle B = 180 - (90 + 45) = 45</em>

Now, since ∠A = 45 = ∠B then ABC is an isoceles right angled triangle at point C

then <em>BC = AC = 14</em>

applying the Pythagorean theorem:

AB=\sqrt{CA^{2}+CB^{2}  } = \sqrt{14^{2}+14^{2}  } = 14\sqrt{2}

Answer:

m∠1 =  81

m∠2 =  99

Step-by-step explanation:

The angles are supplemaentary and therefor sum to 180

3x + (x + 72) = 180

4x + 72 = 180

4x = 108

x = 27

m∠1 = 3x

m∠1 = 27(3)

m∠1 =  81

m∠2 = x + 72

m∠2 = 27 + 72

m∠2 =  99

How does " 7 less than three-fifths of a is b" look
Tcecarenko [31]
Let's do it step by step:
"three-fifths of a" would be 3/5 multiplied by a, as that is how you find fractions of numbers, so we can write that as (3/5)a
"7 less" means we have to subtract 7 from (3/5)a, so we get (3/5)a - 7
Now all we need to do is make it equal to B, so your final answer is
(3/5)a - 7 = b

I hope this helps! I put the 3/5 in brackets just so you didn't mistake it as 3/(5a) :)
