How do I solve for x within a triangle?

ycow [4]4 years ago

Since there are 180 degrees in a triangle and a right angle (signified with the diamond at the top) is 90 degrees, the remaining angles are 180-90=90 degrees. Therefore, 2x+1+5x+5=90=7x+6. Subtracting 6 from both sides, we get 7x=84. Next, we divide both sides by 7 to get x=12

Answer:

x=64

y=54

Step-by-step explanation:

3x+4y=24 4(24-4y\3)+3y=22

x=24-4y/3 96-12y\3+3y=22

x=24-4(54)/3

x=-64 96/3-22=3y/3

y=54

5. Find the squares of the following numbers by using the formula of (a + b)' or (a-b]². c) 98​
Dmitrij [34]

98^2 = (100-2)^2

Using (a-b)^2, we have

= (100)^2-2(100)(2)+(2)^2

= 10000-400+4

= 10004-400

= 9604

The answer is 9604.
