The answer is 30°.
Rule: All three sides must add up to 180°.
Since A=60 and the side vertical to the angle which is 90° then side C would be C=90° and that adds up to 150°, so you can conclude that angle B is 30°.
I hope I helped!

swat32

Answer:

Second option: $2x=90$

Step-by-step explanation:

Let be "x" the number of candy bars Brady sold on Saturday.

For this exercise you need to analize the information provided in the exercise.

According to the information provided, Brady gets paid $2 for every candy bar he sells. This can be expressed as:

$2x$

You know that Brady made a total of $90 on Saturday; this mean the product of $2x$ is 90.

Based on this, you can write the following equation that represents the number of candy bars Brady sold on Saturday:

$2x=90$

Observe that this matches with the second option.

Big will's ice cream cone contains 16 grams of saturated fat. This is 80% of his total daily allowance. What big will's total da

Ahat [919]

Answer:

20 grams

Step-by-step explanation:

Let x be the total allowance of fat

16 grams is 80% of his total allowance

x * 80% = 16

Change percent to a decimal

x *.8 = 16

Divide each side by .9

.8x/.8 = 16/.8

x = 20

Answer:

$\log_{10}(147) = 2.1673$

Step-by-step explanation:

Given

$\log_{10} 3 = 0.4771$

$\log_{10} 5 = 0.6990$

$\log_{10} 7= 0.8451$

$\log_{10} 11 = 1.0414$

Required

Evaluate $\log_{10}(147)$

Expand

$\log_{10}(147) = \log_{10}(49 * 3)$

Further expand

$\log_{10}(147) = \log_{10}(7 * 7 * 3)$

Apply product rule of logarithm

$\log_{10}(147) = \log_{10}(7) + \log_{10}(7) + \log_{10}(3)$

Substitute values for log(7) and log(3)

$\log_{10}(147) = 0.8451 + 0.8451 + 0.4771$

$\log_{10}(147) = 2.1673$

What is the slope of the line?

Blizzard [7]

Answer:

Not enough information given

Step-by-step explanation:

To find the slope, you need two points. You put the values into this formula:

(y_2 - y_1) / (x_2 - x_1) = m

The underscores show which ordered pair, so _2 means the values from the second one.

m stands for slope.
