A right angle = 90 degrees

A round angle = 360 degrees

1. 3 x 90 = 270 degrees

2. 4 x 90 = 360 degrees

3. 1 1/2 x 90 = 135 degrees

4. 2 1/3 x 90 = 210 degrees

5. 2/9 x 360 = 80 degrees

6. 3 3/8 x 360 = 1,215 degrees

Luda [366]

Hey mate ,

here is your answer

**********************

The average between any two rational numbers is also rational.

Find the area of the triangle with the given measurements. Round the solution to the nearest hundredth if necessary. B = 107°, a

Archy [21]

Answer: $105.19 \text{ square cm}$

Step-by-step explanation:

Since, by the SAS formula of finding the area of triangle,

The area of triangle, $A = \frac{1}{2}\times s_1\times s_2\times sin\theta$

Where, $s_1$ and $s_2$ are adjacent sides and $\theta$ is the included angle of these sides

Here, $s_1=22$ $s_2=10$

And, $\theta=107^{\circ}$

Thus, the area of the triangle ABC,

$A = \frac{1}{2}\times 22\times 10\times sin (107)^{\circ}$

$A = 110\times 0.95630475596$

$A = 105.193523156\approx 105.19\text { square cm}$

Therefore, Third Option is correct.

gogolik [260]

Answer:

0.0010,0.2743

Step-by-step explanation:

Given that Stanford–Binet IQ Test scores are normally distributed with a mean score of 100 and a standard deviation of 15

If x represents the scores then

X is N(100,15)

a) See enclosed file

b) Z score = $\frac{x-100}{15}$

c) the probability that a randomly selected person has an IQ test score

i. Over 145.

= $P(X>145) = P(Z>3) = 0.0010$

ii. Under 91

= $P(X$

What is the slope of the line x=9

Lemur [1.5K]

Answer:

"undefined"

Step-by-step explanation:

The slope of any vertical line is "undefined". There is no horizontal change for any vertical change you might like, so computation of the slope involves division by zero. The result of division by zero is "undefined."
