triangle on right is the same as the triangle on the left
use pythagorean theorem
hypotenuse will give to the sides of the rectangle
a^2 + b^2 = hypotenuse squared
10.4^2 = 108.16
15.3^2 = 234.09
342.25 = hypotenuse squared
take the square root in both sides
hypotenuse = the square root of 342.25 =
18.5
add up the areas of the 2 triangles and rectangle
triangle area is 1/2 times 10.4 times 15.3 =
79.56
2 triangles areas are 159.12
rectangle area is 18.5 × 7 = 129.5
159.12 + 129.5 = 288.62
answer 1 = 288.62
second question:
to get 1 side take the
square root of 702.25 which is
26.5
to get the perimeter
multiply 26.5 by 4 which is
106
answer 2 is choice B 106
(A) 1.8
The difference is 18, 13 is bc the tenth term so divide 18 by 10 to get 1.8
It’s 75! 65+40= 105 then 180-105= 75
Answer:
B
Step-by-step explanation:
tan(30)=n/(5*sqrt(3))
=> n=5
Answer:
Its the same formula that your using to find a regular object as an irregular one. The only difference is that your adding the formula of multiple shapes together since an irregular shape consists of multiple regular ones
