Hi there!
We can solve for x knowing that the sum of interior angles in a triangle is 180°.
The square at the bottom indicates a right angle, or 90°. Therefore:
180 = 90 + x + (x + 10)
Combine like terms:
180 = 100 + 2x
Subtract 100 from both sides:
180 - 100 = 2x
80 = 2x
Divide both sides by 2:
x = 40.
Answer: if there are 32 students in the class and 16 are boys so the other half well be 16 girls. 16 + 16 = 32. Sooo the answer is 16 girls
Step-by-step explanation:
Answer:
Option a.
Step-by-step explanation:
An ordered pair is written in the following form: (x, y). It means, first the independent variable and secondly the dependent variable.
In the diagram, the first circle represents the independent variable, and the second circle represents the dependent variable.
Then, the set of ordered pairs is (From left to right)
(-3, 3) ; (0, 0) ; (2, -2).
So the correct option is option a.
It would be 10x10 =100 or in other word 10 times itself. Also known as 10 with the 2 hanging over the 10.
So 4 triangular faces of the pyramid will have total area
<span>= 4 ×<span>12 </span>× base × height = 4 × <span>12 </span>× 34 × 58f<span>t2 </span>= 3944f<span>t2</span></span>
So <span>3944f<span>t2</span></span> of marble cover the faces of the pyramid.
