Answer:

162°

Step-by-step explanation:

They are on a straight line so add to 180

8x + 10 + 2x - 20 = 180

10x - 10 = 180

10x = 190

x = 19

We want AXB so 8x + 10 where x = 19

8(19) + 10 = 162 so it is 162°

Answer:

162 degrees

Step-by-step explanation:

These two angles add up to 180.

8x + 10 + 2x - 20 =180  Next combine the x terms and the constant terms

10x -10 = 180   Next Add 10 to both sides

10x = 190  D  Next divide both sides by 10

x = 19.  Now that we know x, we can solve for <AXB

8x + 10

8(19) + 10

152 + 10 = 162

What is the area of △ABC?
kirza4 [7]
Answer:
Area = 492.4 m²

Explanation:
The area of the triangle can be calculated using the side-angle-side method as follows:
Area = 0.5 * first side * second side * sin(angle included between these two sides)

This rule is illustrated in the attached image.

Now, we have:
AB = 40 m
BC = 25 m
angle B which is the angle included between AB and BC = 80 degrees

The given angle is included between the two given sides, therefore, we can apply the above rule to get the area.
Area of triangle = 0.5*40*25*sin(80)
Area of triangle = 492.4 m²

Hope this helps :)

vaieri [72.5K]

Answer:

1) f(3) means the temperature after 3 seconds

2) f(3) = 22 + 1.3(3) = 25.9

Temperature after 3 seconds is 25.9°C

3) f(t) = 35 means after t seconds, temperature was 35°C

4) 35 = 22 + 1.3t

1.3t = 13

t = 10 seconds
