Answer:
b
Step-by-step explanation:
First find x from the Pythagorean theorem a^2 + b^2 = c^2, where c is the hypotenuse.
7^2 + 24^2 = c^2
49 + 576 = c^2
c^2 = 625, so c = 25
Then to figure out y and z you need to use inverse trigonometric functions.
Use arctan(7/24) = y = 16.3 degrees and arctan(24/7) = z = 73.7 degrees.
1,368 x 10^9th is 1.368 x 10^12
Answer:
12 units
Step-by-step explanation:
From the given figure,
AB=4 units & BC=3 units
By Pythagoras Theorem,
Here,
Thus, AC=5 units
Now, perimeter of triangle is equal to the sum of all sides.
Perimeter = AB + BC + AC = 4 + 3 + 5 = 12 units
2x+0.5 i think this is right
