*assuming that ABC is a straight line**
<span>then you have </span>
<span>AB = 17.89 ..... this is the length of the whole line </span>
<span>BC is a part of the line = 7 </span>
<span>therefore the length of the other part = 17.89 - 7 </span>
<span>= 10.89</span>
so yull do math I'm guna do different number just plug these in for.your numbers 225/(375+x)=25
cross multiply land solve900-375 x=525 then cheak
225/(375+525) = .25
Answer:
Step-by-step explanation:
AB=√(-2-3)²+(6+1)²=√(25+49)=√(74)
Value of x = 19
(8x - 20) = (5x + 37)
3x = 57
x = 19
Answer:
a = 5.07
Step-by-step explanation:
Here, we want to get the value of the side marked a
What we have is a right triangle
so, to find the value of a, we are to use the correct trigonometric ratio
The angle given faces a, which makes a the opposite
the side measure faces the right angle and that makes it the hypotenuse
The trigonometric ratio that connects the two is the sine
The sine is the ratio of the opposite to the hypotenuse
mathematically;
sine 25 = a/12
a = 12 * sine 25
a = 5.07
