Answer:
Step-by-step explanation:
20 + 6 + 30 + 6
or
10(2) + 6(2) + 15(2)
or
25 + 37
Answer:
Solution given;
<ABD=<BAC+<ACB
<u>Since</u><u> </u><u>exterior</u><u> </u><u>angle</u><u> </u><u>of</u><u> </u><u>a</u><u> </u><u>triangle</u><u> </u><u>is</u><u> </u><u>equal</u><u> </u><u>to</u><u> </u><u>the</u><u> </u><u>sum</u><u> </u><u>of</u><u> </u><u>two</u><u> </u><u>opposite</u><u> </u><u>interior</u><u> </u><u>angle</u>
26x+20=19x-15+9x+25
solve like terms
26x+20=28x+10
subtracting both by 10
26x+20-10=28x+10-10
Subtracting both side by 26x
10=28x-26x
2x=10
dividing both side by 2
2x/2=10/2
x=5
Now
<ABD=26*5+20=l50°

It’s A. An quadrilateral has four sides and four angles.
Answer:
x=28
Step-by-step explanation:
cos60°=14/x
0.5=14/x
x=14/0.5
x=28
Hello,
I'm not going to do it for you, I'll explain you how to do it, so you can LEARN something. Like that is the equation of a line, we only need two points to draw it, they can be the x-intercept an y-intercept.
When we are looking for the x-intercept, y=0
And when we are looking for the y-intercept, x=0
Like you can see in the picture, so replace x=0 to find the y-intrcept and y=0 to find the x-intercept and join them, as you saw in the picture and there you have the graph.
If you have any trouble don't hesitate to tell me.
