NEED HELP TRIANGLES 10 POINTS

Find the missing angle measure. then classify the triangle by its angles and by its sides.

iren [92.7K]

Answer:

Part a) The measure of the missing angle is $90\°$

Part b) The triangle of the figure is a right triangle

Part c) The triangle of the figure is a scalene triangle

Step-by-step explanation:

we know that

The sum of the interior angles of a triangle is equal to $180\°$

so

Let

x------> the missing angle

we know that

$x\°+50\°+40\°=180\°$

solve for x

$x=180\°-90\°=90\°$

The triangle of the figure is a right triangle --------> by its angles

Because the triangle has an angle measure of $90\°$

The triangle of the figure is a scalene triangle --------> by its sides

Because the three angles and the three sides measures are different

Given the problem below what mistake did Bob make in solving the equation? Bob and his friends paid $30 for 3 sandwiches and and

storchak [24]

Answer:

Bob forgot to distribute 3 to 1.50 in the parentheses

Step-by-step explanation:

Bob made the mistake in his first step.

In the equation 3(x + 1.50) = 30, the 3 has to be distributed to both x and 1.50.

But, Bob only distributed it to x, which led him to get the wrong answer.

So, Bob's mistake when solving was that he forgot to distribute the 3 to 1.50

What is the slope of a line that contains the two points (0, 3) and (4, 5)?

Anika [276]

The formula for slope is (y2 -- y1) / (x2 -- x1).

(0,3) (4,5)

5 - 4 = 1

3 - 0 = 3

So the slope is 1/3.

Hope this Helps!!

Ramona's Garage charges the following labor rates. All customers are charged for at least 0.5 hr.

algol13

Answer:

a. The linear function is given by,

y = 60x + 30 [y is in $ and x is in hour and x ≥ 0.5]

= 60 [for x < 0.5]

b. The total cost of the repair job is, $ 675 .

Step-by-step explanation:

Let, the linear function describing garage charge( y in $) and no. of hours of repair job ( x in hour) be,

y = mx + c [for x ≥ 0.5] -----------(1)

where, m is the slope of the line and c is the y intercept.

Now ,

m = $\frac {90 - 60}{1 - 0.5}$

= 60 ----------------(2)

Now, putting the value of m and the point (x,y) = (0.5, 60) in (1), we get,

$60 = 60 \times 0.5 + c$ $

⇒ c = 30 ----------------- (3)

Hence, the linear function is given by,

y = 60x + 30 [y is in $ and x is in hour and x ≥ 0.5] ------------(4)

= 60 [for x < 0.5]

Now, putting

x = 4 hr 15 min

= $4\dfrac {15}{60}$ hour

= 4.25 hour in (4), we get,

$y = 60 \times 4.25 + 30$ [in $]

= $ 285

So, the total cost of the repair job,

= $ (285 + 390)

= $ 675
