Answer:

First evening, 21 calls. Second evening, 26 calls. Third evening, 84 calls.

Steps:

T = 4F

S = F + 5

131 = F + S + T

Substitute in the S and T equations;

131 = F + F + 5 + 4F

126 = 6F

F = 21

Then substitute F into both T and S equations;

T = 4 * 21

T = 84

S = 21 + 5

S = 26

Answer:

The no.of call received on the first evening  = 21

The no.of call received on the second evening  = 26

The no.of call received on the third evening = 84

Step-by-step explanation:

Let the no.of call received on the first evening be x.

The no.of call received on the second evening  = x + 5

The no.of call received on the third evening = 4x

x +   x+5   +  4x   = 131

6x + 5 = 131

     6x = 131 - 5

     6x = 126

        x = 126/6

       x = 21

The no.of call received on the first evening  = 21

The no.of call received on the second evening  = 21 + 5 = 26

The no.of call received on the third evening = 4*21 = 84

Give that m/_ y=39, find the measures of angles a and b
Amanda [17]

Answer:

  ∠a = 39°

  ∠b = 129°

Step-by-step explanation:

Vertical angles are congruent. An exterior angle of a triangle is equal to the sum of the remote interior angles.

<h3>Application</h3>

Angle y and angle 'a' are vertical angles, so congruent.

  ∠a = ∠y = 39°

The angle marked 'b' is an exterior angle to the triangle. Its remote interior angles are 'a' and the one marked 90°.

  ∠b = ∠a +90° = 39° +90°

  ∠b = 129°

valentinak56 [21]

Answer:

tan(θ) = 0, 0.577, -0.577

Step-by-step explanation:

3tan³(θ) - tan(θ) = 0

tan(θ)(3tan²(θ) - 1) = 0

tan(θ) = 0

tan²(θ) = ⅓ tan(θ) = +/- sqrt(⅓)

tan(θ) = 0, sqrt(⅓), -sqrt(⅓)

tan(θ) = 0, 0.577, -0.577

To find θ values, domain is required

Hello,

A=(4,2)
B=(2,8)

(AB)≡y-2=(x-4)*(8-2)/(2-4) ==> y=-3x+14
