Use the fact that the sum of angle measures in a triangle is 180.
Equation: x+35+45=180 Missing Measure: 100^(∘)
Practice makes perfect
We want to write and solve an equation to find the missing measure x in the given triangle.
To do this, we can use the fact that the sum of the measures of the angles of a triangle is 180^(∘).
Let's use this fact to write an equation by adding the given measures and setting the sum equal to 180.
x+ 35+ 45=180
Now, let's solve the equation for x.
