Answer:
840cm²
Step-by-step explanation:
The two small triangle areas:
b × h / 2 = 12 × 5 = 60 / 2 = 30cm²
So two triangles would be 60cm²
Now, for the top rectangle:
b × h = 26 × 12 = 312cm²
The middle rectangle:
b × h = 26 × 13 = 338cm²
And the bottom last triangle:
b × h = 26 × 5 = 130cm².
Now to add them all: 60 + 312 + 338 + 130 = 840cm²
I advice you to just check to make sure the calculations were right! Good luck with the rest of your finals :)
Answer:
52°
Step-by-step explanation:
The measure of angle between the ladder and the ground is given as:
Sum of angles in a triangle
38° + x° + 90° = 180
128°+X° = 180°
X° = 180-128
X= 52°
Hence the angle x = 52°
Answer:
x=5
Step-by-step explanation:
9+5x=6x+4
-5x -5x
9=1x+4
-4 -4
5÷1=1x÷1
5=x
Answer: B 1/3
Step-by-step explanation:
For every 3x it travels 1 y so you will get 1/3 as your answer.
At 50y the line is at 10x. By the time it is at 60 y it is at 40x. This was a change in y by 10 and change in x by 30. There fore the answer is 10/30 or 1/3.
A postulate is a true statement that does not require to be proved . Also called an axiom.
