I think its B not sure tho sorry
Well I THINK triangle ABC is just a stretched out version of triangle DEF.
To find the area of a triangle, you multiply base and height, and divide by 2.
Area of DEF is 6, so that means that (4 * x)/2 = 6.
6*2 = 12....
4 * x = 12........
4 * 3 = 12.
x = 3.
Comparing DEF to ABC: ABC's base is 3 times as long as DEF's. So that means the height must be three times as long.
3*3 = 9.
(12 * 9)/2 =54
Answer:
21 in
Step-by-step explanation:
by the Pythagorean theorem we have
notice that the 841 and the 400 don't go squared because they already squared!
Answer:
Add
7 to both sides.
6x=5+76x=5+7
2 Simplify 5+75+7 to 1212.
6x=126x=12
3 Divide both sides by 66.
x=\frac{12}{6}x=
6
12
4 Simplify \frac{12}{6}
6
12
to 22.
x=2x=2
Done
