Im assuming the height is dropped so that it is the halfway point. this would then make the base 5cm, with a height of 12cm. if that is the case then the answer should be 13
Answer:
Ans= 6720 ways
Step-by-step explanation:
From Combination rule from Permutation and Combination, nCr
We use 8^C3 or 8C3,
8x7x6x5x4x3x2x1
-------------------------- =6,720
3x2x1
or
8x7x6x5x4x3! /3!, here the 3! cancels each other out, and we're left with 8x7x6x5x4, which equals 6720.
Answer:
=561.2 square feet
Step-by-step explanation:
top rectangle=19×8=152
bottom rectangle=5×8=40
two slanting rectangles=8×14×2=224
two side trapezium=(19+5)÷2=12
1/2×12×12.1×2=145.2
add them all
152+40+224+145.2=561.2
Answer:
x = 50, y = 140
Step-by-step explanation:
The angles x, 40 and 90 lie on a straight line and sum to 180° , that is
x + 40 + 90 = 180
x + 130 = 180 ( subtract 130 from both sides )
x = 50
The angle vertically opposite x is congruent to x , that is 50°
y = 90 + 50 = 140
Answer:
The angles are 91 and 89 degrees
Step-by-step explanation:
Supplementary angles add to 180 degrees and 91 is 2 more than 89
