Answer:
CAB = 70°
YZW = 120°
Step-by-step explanation:
CBA = 90° (right angle in a semicircle)
CAB = 180° - CBA - ACB ( angle in a triangle is 180°)
CAB = 180° - 90° - 20°
= 70°
YZW + YXW = 180° (opposite angle are supplementary in a cyclic quadrilateral)
YZW = 180° - YXW
= 180° - 60°
= 120°
(Correct me if i am wrong)
Answer: -42
Step-by-step explanation:
-4(n-6)+m
and then they give you the values of each
basically what you do is put the value of m into where it shows on the equation as well as the n.
-4(-5-6)+2 and then you should get
-42
Answer:
4.243
Step-by-step explanation:
To calculate the diagonal of a square, multiply the length of the side by the square root of 2:
d = a√2
d = 3√2=4.24264068
P=18 because 3 times two is 6 and 4 times 3 is 12 so when you add them you get 18
