Answer:
B. 55°
Step-by-step explanation:
Note that the total angle measurements of a triangle is = 180°.
Add all the measurements together:
40 + y + 30 + y = 180
Simplify. Combine like terms:
(40 + 30) + (y + y) = 180
70 + 2y = 180
Isolate the y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First subtract, then divide.
Subtract 70 from both sides:
70 (-70) + 2y = 180 (-70)
2y = 180 - 70
2y = 110
Divide 2 from both sides:
(2y)/2 = (110)/2
y = 110/2
y = 55
B. 55° is your answer.

Answer:
OGH and TCA
Step-by-step explanation:
that's quite easy...
the congruency criterion is ASA or Angle side Angle.
i.e. a side lying between two Angles.
so we have
GH = FN= CA
now, G=I= C
and H=N=A
it's pretty clear that G-GH-H = C-CA-A
(just to explain)
hence, the answer
Answer:
55 cm^2
Step-by-step explanation:
Find the area of the large rectangle
A = l*w = 9*7 = 63 cm^2
Then find the area of the unshaded rectangle
A = l*w = 4*2 =8cm^2
Subtract the unshaded area from the large rectangle
63 - 8 =55 cm^2
The shaded area is 55 cm^2
Triangle will be formed. base = 5-(-3)= 5+3=8 ( lies on the X axis ) height = 4 Area of triangle = base *height/2 =8*4/2= 16 sq. units
