Answer:
m∡GHI = 21°
Step-by-step explanation:
Since the lines are intersecting, GHI and JHK are opposite angles, so they are the same measure.
That means you can set them equal to each other
x + 7 = 3x - 21
x = 14
Now plug x into GHI
14 + 7 = 21
m∡GHI = 21°
Answer:
3060°
Step-by-step explanation:
19-2 = 17
17 x 180 = 3060
Given:
A right triangle on a coordinate plane.
To find:
The area of a triangle.
Solution:
We know that, the area of a triangle is
From the given figure it is clear that the base of the triangle is 4 units and the height is 3 units. So, the area of the given triangle is
The area of the given triangle is 6 units². Therefore, the correct option is B.
When putting numbers into scientific notation, always put the decimal after the ones place. In this case, you would put the decimal after 4 and before 5 (in between). From there, you count how many decimal places you moved in order to change it into that form.
0.45013 would change to 4.5013 and you would have to multiply it by 10 to the negative power of 1 (you're only moving back one place).
4.5013 x 10^-1
Hope this helps :)
