Answer:
you know that sin 90 is 1 and cos 45 is 1/√2
so,
Answer:
14x
Step-by-step explanation:
<em>You have two like terms (numbers with the same letter) so you are going to put those aside for a moment.</em>
<u>Add 5+7+2 </u>and you get 14.
Then, You put the unknown number (x) just beside the 14 to know you are <u>multiply</u>ing <u>x by 14</u> until you find the value.
14x <em>Is your answer</em>
<h3>Please give me brainliest</h3>
So when you opened up the parenthesis on the right side of the question, you added -2 to 5 instead of multiplying. Since there is no addition sign in between -2 and the parenthesis, it should be multiplication, so -2x + -10.
So now the answer would be 10 = -10.
Which leads me to believe that this question wasn't written correctly because 10 does not equal -10 for sure.
Answer:
PA+AR=PR
AR= PR- PA
AR= 8x+14-(7x-11)
AR= 8x+14-7x+11
AR= x+25
Now, if A is midpoint of PR, then
PA=AR
7x-11= x+25
6x=36
x=6
Put value of x in AR
AR= 6+25= 31
Hope this will help:)
