Answer:
I believe the answer is D
Step-by-step explanation:
D I believe because if you look at point B it is (3,3) but dilated to (9,9) and 9/3=3. Which also means that the side lengths will be 3 times the original triangle’s side lengths
When you are adding a negative number you subtract it. The equation can be rewritten as:
45.23-7.89=37.34
When subtracting numbers with decimals, think of it like subtracting whole numbers but with a decimal point.
45.23
- 7.89
37.43
Your answer is 37.43.
Answer:
x = 7
x = 16
x = √(89)

tan(angle) = opposite/adjacent

cos(angle) = adjacent/hypotenuse

a² + b² = c²
If you're given an angle and 1 side then you can use sin(), cos(), or tan() to solve for the other missing side.
If you're given two sides then you can use the pathagorean theorem, a² + b² = c², to solve for your missing side.
Explanation:
If two triangles are congruent, this means they are the same shape and the same size.
By definition, all corresponding angles of two congruent triangles are congruent. Additionally, all corresponding sides of two congruent triangles are congruent.
When we know that two triangles are congruent and are showing that corresponding sides or corresponding angles of the triangles are congruent, we use the justification "CPCTC". This stands for:
<em>C</em><em>orresponding</em>
<em>P</em><em>arts of</em>
<em>C</em><em>ongruent</em>
<em>T</em><em>riangles are</em>
<em>C</em><em>ongruent</em>.
