Hello there!

The answer to this question will be answer choice A.

When using the SAS postulate, we need two pairs of sides and the pair of the angles between those two sides to be congruent.

It is given that one pair of sides are congruent, along with a pair of congruent angles.

We want the congruent angle to be between two congruent sides, thus AC must be congruent to EC in order for these triangles to be proven congruent by the SAS postulate.

Hope this helps and have an awesome day! :)

When viewed from the front, the rope used to tie down a tent forms a pair of supplementary angles with the ground. Find $m\angle
pentagon [3]

Answer:

<ABC = 49°

Step-by-step explanation:

The sum of two supplementary angle is 180. From the diagram, the two angles are 3x+4 and 8x+11. IF this two angles are supplementary then;

3x+4+8x+11 = 180

11x+15= 180

11x = 180-15

11x = 165

x = 165/11

x = 15

From the attached diagram, <ABC = 3x+4

<ABC = 3(15)+4

<ABC = 45+4

<ABC = 49°

STALIN [3.7K]

Answer:

97.27^{o}F

Step-by-step explanation:

We have been given that human body temperatures have a mean of 98.20° F and a standard deviation of 0.62°. Sally's temperature can be described by z = -1.5.

To find Sally's temperature we will use z-score formula.

z=\frac{x-\mu}{\sigma}, where \mu = Mean, \sigma= Standard deviation.

Let us substitute our given values in z-score formula.

-1.5=\frac{x-98.20}{0.62}

Multiply 0.62 to both sides of equation.

0.62\times-1.5=0.62\times \frac{x-98.20}{0.62}

-0.93=x-98.20

Add 98.20 to both sides of equation.

-0.93+98.20=x-98.20+98.20

97.27=x

Therefore, Sally's temperature will be 97.27 degrees Fahrenheit.
