Your second option here works perfectly for it. If you plug in each input it equals the outputs in order. </span>
Answer:
1. BC = 18
2. m<ABC = 80°
3. x = 5
Step-by-step explanation:
1. If DE = 9, therefore:
(based on the midsegment theorem, DE is half the length of the third side, BC)
2. m<ADE = 80°, then,
m<ABC = 80°
This is because m<ADC and m<ABC are corresponding angles. Corresponding angles are congruent.
3. DE = 2x + 7 , and BC = 7x - 1, find BC
Thus:
(midsegment theorem)
(substitution)
Solve for x
Collect like terms
Divide both sides by 3
x = 5
The only things you can factor out of here is a 3 so you are left with:
3(y-6)
Hope that helps.
.78 + 10% = .858 Hope this helps!!
[2] Angle BOC is complementary to angle COD because a complementary angle is 2 angles whose sum is 90°, and angle COD is 45° and if you look at angle BOC you'll see that it also equals to 45°. 45° + 45° equals to 90°, which is why Angle BOC [2] is the answer.
