<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°

to get percent, move the decimal point over two spaces to the right:
32.6%
to get fraction, put it over 100 by moving the decimal spaces two to the right:
32.6/100
To get a fraction that is not include a decimal, write it over 1000 (at this case:
326/1000
hope this helps
Answer:
24
Step-by-step explanation:
(72/-9) / (-1/3)
72/-9) x (-3/1)
(72)*(-3) = - 216/ -9
= 24

3969
- 3600 = 369 square root of the 369= is 19.2
Answer:
See graph in attachment
Step-by-step explanation:
We want to graph the function,
First, let us rewrite the function in the vertex form;
The parabola opens downwards because
The vertex of the parabola is .
At y-intercept, .
This implies that,
At x-intercept,
This implies that;
This equation has no real number solutions because of on the right hand side. This implies that the graph has no x-intercepts.
We therefore draw a maximum graph through the vertex and the y-intercept to obtain the graph in the attachment.
