Special right triangles 45-45-90 & 30-60-90 formula!! finding missing side lengths

Mathematics

The formula you need to know is that the side opposite of the 30° angle is always half the hypotheneus. For example in question 2 X should be 6 since 3 is opposite side of the angle 30°. In a 45 45 90 triangle, it is important to know that the straight sides are always the same length (since they are the same angle). For example in question 9, v is also 9√2.

When you have two sides, you can figure out the third side with a² + b² = c² since they are all right triangles. Good luck

What is the answer to adding 3/14 1/7
sp2606 [1]

Hello There!

The answer to adding 3/14 and 1/7 together give you a sum of 5/14

STEP #1 <em>The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.</em>

STEP #2 Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

<h2>(3/14*1/1) + (1/7*2/2)</h2><h2 /><h2><em>3/14 + 2/14 = </em><u><em>5/14</em></u></h2>

Write an inequality for the graph.
gregori [183]
First of all, the shaded part is under the line, so it is a smaller than, so we can eliminate D
next, look at the vertex, it is at (5,5), which means when x=5, whatever is inside the absolute symbol has a value of zero, and y will be 5
so the answer is A
