Answer:
A = 30
Step-by-step explanation:
The area of a triangle is 
Plug in the values given:
A = 1/2 (10) (6) = 1/2 (60) = 30
well first you should work on the rectangle so since that is l x w
You would do 12*18 which would be 216
so now you got the area of the rectangle now since we know the base and height of the triangle you would do 7*18*1/2 which would be 28
so now you add 216 and 28 which would be 244 which would be your answer
hope this helps
P.S the base of the triangle is the width of the rectangle in this problem
A) 2o+5l=2.75
-2o-9l = -4.15
———————-
-4l=-1.4
l= 0.35
2o+5(0.35)=2.75
2o+ 1.75= 2.75
2o=1
O= 1/2
B) 5(0.5) + 3(0.35) = 2.5+1.05= 3.55
Answer:
<h2>The arc length is 4 cm to the nearest cm</h2>
Step-by-step explanation:
The diagram is not given in this question, but we can proceed anyways.
from the problem statement we can observe that the radius of the arc is same as the width of the door
a. the radius is 4.2 cm
b. the length of the arc given that the central angle is 25° can be gotten using the formula stated bellow
arc length = 2 π r *(∅/360)
substituting we have
arc length = 2*3.142*(225/360)
arc length= 6.284*0.625
arc length=3.92 cm
<h2>Approximately the arc length is 4 cm</h2>
