Triangle ABC is an isosceles right triangle. What is the measure of a base angle?
Answer:
The measure of base angle is 45°
Step-by-step explanation:
Given that triangle ABC is an isosceles right triangle.
we have to find the measure of base angles.
As given triangle is right angled triangle therefore one angle which is not a base angle is of 90°
Also the triangle ABC is isosceles therefore two sides of triangle are equal and angles opposite to the equal sides are equal.
Let these equal angles which are base angles is x°
By angle sum property of triangle,
the sum of all angles of triangle equals to 180°
∠A+∠B+∠C=180°
Hence, the measure of base angle is 45°

Answer:
35.1
Step-by-step explanation:
There's a formula that i've linked as an image
Basically, substitute all 3 sides and the length into that formula, chuck it into the calculator and viola.
Or... we can use pythagoras' theorem and get the height of the triangle Height = - = 2.6
Area of triangle = (3 * 2.6) / 2 = 3.9
Volume = 3.9 * 9
Volume of prism = 35.1

The least common denominator is 20p
.
The first fraction rewritten with the LCD is 20p^2+30 / 20p^2
The second fraction rewritten with the LCD is 4p - 4 / 20p
The sum is 24p^2-,4p+30 / 20p^2 = 12p-2p+15 / 10p^2
The sum is a rational expression.
