Answer: x=9
Explanation: All 3 angles of a triangle add up to 180, so basically the equation is (3x-5)+(7x+5)+90=180.
Then you add your like terms, so 3x+ 7x=10x and -5+5=0, which cancels out. Now we have 10x+90=180, we subtract the 90 from 180 to see what 10x is equal to and we get 90. So 10x=90. We divide 10 from 90 and we get the value of X, which is 9.
Hey there!
If x = 3 then substitute it into the equation
3(3) = 9
3(3) = 9
9 = 9
Answer: 9 = 9, so this makes this statement is true
Good luck on your assignment and enjoy your day!

85 / 5
(50 + 35) / 5 =
(50/5) + (35/5) =
10 + 7 = 17
Answer:
7/10.
Step-by-step explanation:
If theres a total of 10 games and 7 out of the 10 are racing games, it means that 7/10 of the games are racing games.
First, all the heights have to be converted to similar units, say feet.
Therefore,
Building= 20 feet
Tree = 252*0.083333 = 21 feet
Flagpole = 6*3 = 18 feet
The tallest of the three is the tree and thus should cast the longest shadow. However, it should be noted that at exactly noon when the sun is overhead, all the three will have equal length of shadow (that is, 0 feet long).
