Answer:
x = 7
Step-by-step explanation:
I think there may be other ways to do this ... but this is one I guess....
one angle= 90 ( given)
the other = 45 (given)
the third = 90 + 45 + a = 180
(all angles of triangles is 180 [angle sum property])
a = 180 - 135
= 45
The base angles are equal so that means it is a isoscles triangle. In isoscles triangle, two sides are equal , so
if one side is 7
the x is 7 too
(as it cant be the hypothenus)
I think this is right
You would have a right triangle where the hypotenuse is 51. To figure out this problem we can use the Pythagorean theorem- a^2 + b^2 = c^<span>2. so the equation should be 50^2+b^2=51^2
</span>50^2+b^2=51^2
2500+b^2=2601
b^2=101
b=10.049875621121xx
The answer is -3. Now imagine a line of numbers from -4 to +4. Your first number in that line would be +2. From there you would be moving to the left since you're taking numbers away and in this case you're taking away +5. So when you're going on that line from +2 tho the left by +5 it gets you to -3. I hope you understand what I'm trying to say:D I also included the photo of that "line".
(j+5)*8 is what you're looking for. The braces are important.
You could also write as 8j + 40.
