Answer:
If angle B measures 25°, the approximate perimeter of the triangle is 10.48 units. A right triangle is shown. Angle A is 90 degrees and angle B is 25 degrees.
Step-by-step explanation:
7 9/12 = 7.75
2 11/12 = 2.917
So we can round both of these up.
7.75 rounds to 8
2.917 rounds to 3
8 + 3 = 11
So the estimated sum is 11.
7 9/12 + 2 11/12 = 10 2/3
So the actual sum is 10 2/3.
The estimated sum is a pretty good estimate to the original number.
Divide the arrow into upper triangle and lower rectangle
area of triangle :-
area of rectangle :-
add both the area :-
area of triangle+ area of rectangle = area of arrow
310 + 300 = 610 cm²
