must be parallel
Step-by-step explanation:
They must be parallel.
Answer:
x = 25 ft
Step-by-step explanation:
here we see the student standing and creating a small triangle that is equivalent to the big triangle since it has the same angles, the only difference is that its smaller, so what we have to do is make a proportion of both triangles, so since 8 ft correspond with the 40 ft they're going to be in the same part of the proportion and the other measurements, including x, on the other part, so itll be 5/8 and x/40, see how the 8 and 40 are both on the bottom? thats because they correspond, so now all you have to do is cross butterfly, so you can set up an expression on 8x= 5*40 or you can just multiply 5*40 and then divide by 8, your answer will be x= 25 ft
Answer:
a = 115, b = 71
Step-by-step explanation:
The figure has one pair of parallel sides and is a trapezium.
Using a property of trapeziums
• each lower base angle is supplementary to the upper base angle on the same side.
a = 180 - 65 = 115
b = 180 - 109 = 71
