1. x=-3 y=4 2. x=5/2 y=15/2 3. x=9/5 y=-36/5 4. x=-2 y=1
Answer - C. The ratio of the corresponding sides will be equal
Two triangles<span> can be shown to be </span>similar<span> if it can be proven that they have two sets of corresponding sides in equal proportion and that the corresponding angles, which they include are congruent.</span>
Answer: (6 x 2) - (4 x 5) + (12 / 4)
Area=1/2bh
h=altitude
b=legnth of base
b is 3 times h
b=3h
divide by 3
b/3=h
area=1/2bh
subsitute b/3 for h
54=1/2(b)(b/3)
multiply bothsides by 2/1
108=b(b/3)
108=(b^2)/3
multipy both sides by 3
324=b^2
square root boh sides
18=b
legnth of base=18
Answer:
x=12
Step-by-step explanation:
Since the triangle is isosceles, the 2 base angles are congruent.
Also, the interior angles of a triangle add up to 180.
32+7x-10+7x-10=180.
Solve.
14x+32-20=180
14x+12=180
14x=168
<u>x=12</u>
