Answer;
3/4=-1/2-y
Step-by-step explanation:
y=- 5/4
Answer:
135 degrees
Step-by-step explanation:
It is as isosceles trapezoid, so the the base angles are congruent. The sum of the inner angles is 360 degrees
2(4x-7) + 2(11x -8) = 360
8x - 14 + 22x -16 = 360
30x = 390
x = 13
angle F = angle G
angle G = 11 * 13 - 8 = 135 degrees
The lowest common denominator is 340.
Answer:
area of trapezium=1/2 ×20(38+18)=560cm²
