Answer:
I just answered this in the other equal post.
Pythagoras; a^2 + b^2 = c^2 So, (6.7)^2 + (5.5)^2 = 75.14 then square root to get, 8.668 (to 3 d.p) hope this helps!!
Answer: A. 5x+x+18 = 180
Step-by-step explanation:
For B you need to find the value of x first.
5x + x + 18 = 180 is your equation.
Combine like terms: 5x+x = 6x
Equation should now look like this
6x + 18 = 180
Subtract 18 to both sides 180-18 = 162
Do 162/6 = 27
X = 27
WE ARE NOT DONE!!!!!
1. 5(27) = 135
2. 27+18 = 45
Angle 1 = 135
Angle 2 = 45
