Answer: it's just a black screan
Step-by-step explanation:
Answer:
Solution given;
<M=5x+10
<R=55
<M+<R=90°
<u>5</u><u>x</u><u>+</u><u>1</u><u>0</u><u>+</u><u>5</u><u>5</u><u>=</u><u>9</u><u>0</u><u>°</u><u>[</u><u>is</u><u> </u><u>a</u><u> </u><u>required</u><u> </u><u>equation</u><u>]</u>
<u>now</u><u> </u><u>solving</u><u> </u><u>it</u>
<u>5</u><u>x</u><u>=</u><u>9</u><u>0</u><u>-</u><u>6</u><u>5</u>
<u>5</u><u>x</u><u>=</u><u>2</u><u>5</u>
<u>x</u><u>=</u><u>2</u><u>5</u><u>/</u><u>5</u>
<u>x</u><u>=</u><u>5</u><u>i</u><u>s</u><u> </u><u>your</u><u> </u><u>answer</u><u>.</u>
This problem could be set up algebraically or you could use trial and error.
a) 9 and 4 (9 + 4 = 13, 9 * 4 = 36 and 36 - 23 = 13)
I won't give you the rest of the answers, but the second and third ones have to add together to equal a negative number and multiply to equal a positive number. I hope this helps some.
