The area of a triangle for one of the legs being 3 inches and the hypotenuse being 9 inches is 12.727 square inches
<em><u>Solution:</u></em>
Given that to find area of a triangle for one of the legs being 3 inches and the hypotenuse being 9 inches
From given information,
Let "c" = hypotenuse = 9 inches
Let "a" = length of one of the leg of triangle = 3 inches
To find: area of triangle
<u><em>The area of triangle when hypotenuse and length of one side of triangle is given:</em></u>
Where, "c" is the length of hypotenuse
"a" is the length of one side of triangle
Substituting the given values we get,
Thus area of triangle is 12.727 square inches
Problem 1
Answer: Choice B. X is greater than or equal to 4
The closed circle at 4 indicates that this value is included in the solution set. So we will have an "or equal to" as part of the answer. The shading to the right suggests "greater than". Combine "greater than" and "or equal to" and we have a "greater than or equal to" sign.
===================================================
Problem 2
Everywhere is shaded but -4 on the number line. So x can be any number but -4. The answer isn't listed (probably got cut off), but it should be (x is not equal to -4). The slash through the equal sign means "not equal to"
