This figure is not the best, but I'll try my best here
Since BC is parallel to BE (BC is part of BE) and BA is part of BD, two sides are parallel, making two angles congruent and the triangles therefore similar.
Since BA correlates to BD (they are parallel), we can use the knowledge that BA is 7 and BD is 42 to find the scaling factor to be 42/7 =6 from ABC to DBE. Since BC correlates to BE, BC = 10, and the scaling factor is 6, BC*6=BE= 60 = height
<u>Answer</u>
C = 12
<u>Explanation</u>
Ratio is a division. For the two ratios to be proportional, then they must be the same after been simplified to their simplest form.
7/C = 35/60
35 has been divided by 5 to get 7. 60 must also be dived by 5 for the ratios to be proportional.
60 ÷ 5 = 12
∴ C = 12.
7/12 = 35/60
Answer:
H
Step-by-step explanation:
Sum of angles in a triangle is 180 degrees
That means
180= 25 + 45+ unknown angle
180= 70 + unknown angle
180 - 70 = unknown angle
110 = unknown angle
Answer:
Step-by-step explanation:
Each term of the given arithmetic sequence is 6 more than the previous one. Thus, the next term is 26+6, or 32.
a(n) = 8 + 6(n-1)
