substituting into the formula , we have
Answer:
Step-by-step explanation:
The triangles are set up so we see that angle A and angle D are congruent. We also know that, by the definition of vertical angles, angles CED and BEA are congruent. That means, by the Triangle Angle-Sum Theorem, that angles C and B are also congruent. That does NOT mean, however, that the triangles are congruent because their corresponding side lengths are not the same. What it does mean is that the triangles are similar. If we were to pull them apart and set them next to each other, our triangle similarity statement would be that ΔECD ~ ΔEBA. That means that their corresponding sides exist in proportion to one another. Namely, side ED is proportional to side EA, and side CD is proportional to side BA. That's all we need to find the length of BA, the distance across the lake. The proportion is set up like this:
and fill in the distances:
Cross multiply to solve for BA:
400BA = 420000 so
BA = 1050 feet
| x + 2 | + 16 = 14....subtract 16 from both sides
| x + 2 | = 14 - 16
| x + 2 | = -2
answer is NO SOLUTION because an absolute value cannot equal a negative number
Answer:
x+2x-3
because nates car is x and mayas is 2x-3
Answer:
36/19
Step-by-step explanation:
So to find this answer you have to divide 12 by 6 1/3. To figure that out I first turned 6 1/3 into an improper fraction (19/3) and then I put 12 over 1. To divide a fraction you have to multiply the dividend by the divisors reciprocal in this case 12/1 x 3/19 which equals 36/19 or 1 and 17/19
Hope this helps lol :D
