Elena-2011 [213]4 years ago
5 0

Answer:

Step-by-step explanation:

1). m∠AEC = m∠AEB + m∠BEC

                  = 21° + 37°

                  = 58°

2). m∠BED = m∠BEC + m∠CED

                   = 37° + 44°

                   = 81°

3). m∠IKF = m∠IKH + m∠HKG + m∠GKF

                = m∠IKH + m∠HKG + m∠IKH [Since, ∠IKH ≅ ∠GKF]

                = 2∠IKH + m∠HKG

         103° = 2∠IKH + 41°

   2(∠IKH) = 103 - 41

 m(∠IKH) = 31°

4). m∠AED = m∠AEB + m∠BEC + m∠CED

                  = 21° + 37° + 44°

                  = 102°

5). m∠JKG = 108°

    m∠JKG = m∠JKI + m∠IKH + m∠HKG

    108° = m∠JKI + 31° + 41°

    m∠JKI = 108° - 72°

    m∠JKI = 36°

6). m∠HKF = m∠GKF + m∠HKG

                  = m∠IKH + m∠HKG [Since, m∠GKF = m∠IKH]

                  = 31° + 41°

                  = 72°

7). m∠NQO = m∠MQN = 64°

8). m∠JKF = m∠JKI + m∠IKF

                 = 36° + 103°

                  = 139°

8). m∠MQO = 2(m∠NQO)

                    = 2(64)°

                    = 128°

9). m∠LQO = 156°

    m∠LQM = m∠LQO - m∠MQO

                    = 156° - 128°

                    = 28°

10. m∠NQP = m∠NQO + m∠OQP

                   = 64° + m∠LQM [Since ∠OQP ≅ ∠LQM]

                   = 64° + 28°

                   = 92°

svetoff [14.1K]

Answer:

20%

Step-by-step explanation:

1/5 of 1 hour = 20 minutes

so 1/5 = 20%

25% + 20% = 45%

0.35 = 35%

45% + 35% = 80%

100% - 80% = 20%

Answer = 20%

Hope this helps!

alukav5142 [94]

Answer:

x = 5

Step-by-step explanation:

Given

8 = \frac{5x-1}{3}

Multiply both sides by 3 to clear the fraction

24 = 5x - 1 ( add 1 to both sides )

25 = 5x ( divide both sides by 5 )

x = 5

Answer:

the quickest way would be to "complete the square"

on x^2 + 5x - 7

you will end up with  (x+2.5)² = 13.25

or

 y =  (x+2.5)²-13.25    

the vertex

VERTEX: (-2.5,-13.25)

Sunny_sXe [5.5K]

Answer:

170.56\ soles

Step-by-step explanation:

The question in English

1.5 hours for tuning; 0.2 hours for cleaning the battery; 0.75 hours for changing the oil and engine filter; 1.45 hours for changing and aligning lights; and 1.3 hours for repairing the air conditioning system. The hourly rate is 32.8 soles; how much does it cost to repair the car?

step 1

Sum the hours to repair the car

(1.5+0.2+0.75+1.45+1.3)=5.2\ hours

step 2

Find the cost

Multiply the total hours by 32.8\frac{soles}{hour}

so

5.2(32.8)=170.56\ soles
