Answer:
∡A = 48°
∡B = 58°
∡BCA = 74°
Step-by-step explanation:
start by finding m∡BCA; this angle is supplementary with ∡BCD and the pair must add up to 180. therefore, m∡BCA = 74°
all three interior angles of a triangle must add up to 180:
74 + 4y + 3y + 22 = 180
96 + 7y = 180
7y = 84
y = 12
substitute '12' for 'y' in 3y + 22 to get 58
substitute '12' for '4y' to get 48

Answer
Find out the how long are the two line segments together answer in cm .
To prove
As given
i am measurng two line segments the first line is 30centimeter long.
The second line segment is 500 millimeter .
As
1 millimeter = 0.1 centimeter
Now convert 500 millimeter into centimeter .
500 millimeter = 500 × 0.1 centimeter
= 50 centimeter
Thus second line segment be 50 centimeter long .
Total length of two line segments = 30 + 50
= 80 cm
Therefore the 80 cm long are the two line segments together answer in cm .
