Answer:
Step-by-step explanation:
All triangles = 180 degrees
^ That is known.
98 + 45 = 143
^ These 2 angles are given (98 and 45)
180 - 143 = 37
^ This was the total.
37 is the final answer.

37
all triangle's angle measures add up to 180
180-98-45 = x
x = 37
Answer: y = -0.2x + 1
Step-by-step explanation: Find the y intercept (b) and then find the slope (m) and use the equation y = mx + b.

I have attached the images above
A=1+1+2ha+2hb
A=2+2ha+2hb
A=2ha+2+2hb
A=<u>4ha</u>+<u>2hb</u>
4 = 4
A=½
