Answer:
the answer is 160 that the answer
Jo's Number is 20.
Step-by-step explanation:
4 - ( 9 x ? ) = 176.
9 x 20 = 180.
9 x 20 = 180, then subtract 180 by 4.
180 - 4 = 176.
Therefore, Jo's number is 20.
-5 - x = 25
add -5 to both sides
-x=-20
x=20
X= 143°
You could do it your way or as you can see, there's a right angle, which equals 90°, so you could either add 44+46+53 or 90+53. You get the same answer, which is 143°.
