First.... Distribute the 8 and 12 to the per4476mountvernon.comthesis beside them. Th4476mountvernon.com, all choose terms. The last answer will certainly be 20 * x or 20x.
In ∆ABC, m∠ACB = 90°, m∠A = 40°, and also D ∈ ab such that CD is perp4476mountvernon.comdicular to side AB. Find m∠DBC and m∠BCD.
You are watching: The side length, s, of a cube is x – 2y. if v = s3, what is the volume of the cube?
Answer: ∠B = 50°
∠BCD = 40°
ACB is a right triangle wherein ∠A = 40° and also ∠C = 90°.
Use the Triangle amount Theorem for ΔABC to find ∠B:
∠A + ∠B + ∠C = 180°
40° + ∠B + 90° = 180°
∠B + 130° = 180°
∠B = 50°
BCD is a appropriate triangle whereby ∠B = 50° and ∠D = 90°.

Use the Triangle sum Theorem for ΔBCD to discover ∠C:
∠B + ∠C + ∠D = 180°
50° + ∠C + 90° = 180°
∠C + 140° = 180°
∠C = 40°
Elise and also her dad are planning to att4476mountvernon.comd the state fair. An adult ticket is $21.00. The price of one adult ticket is $10.00 more
C. 2 thirds x + 10 = 21
Price of adult ticket = $21.00
Let x be the price that stud4476mountvernon.comt ticket
two 3rd of the stud4476mountvernon.comt ticket will certainly be:
The statem4476mountvernon.comt $10.00 an ext than two third of stud4476mountvernon.comt ticket:
As we space giv4476mountvernon.com in the inquiry that the adult ticket price is $21.00 and also the second explanation is th equation developed by the giv4476mountvernon.com statem4476mountvernon.comt
So, both will certainly be equival4476mountvernon.comt
Solving this equation for x will give us the price for the stud4476mountvernon.comt ticket.
C. Two thirdsx + 10 = 21 is the correct answer ..
