Find the measure of the indicated angle
Margarita [4]

Answer:

the unknown angle is 88°

Step-by-step explanation:

the exterior angle of a triangle is equal to the sum of the opposite interior angles. Therefore, in the tall triangle, 60 + 40 = 100, meaning the bottom left angle in the small triangle is 100-64=36. And b/c angle sum of a triangle is 180°, 180-36-56=88°

Find the midpoint of X (26,56) and Y (26,1)
Svetradugi [14.3K]

Answer:

(26, \frac{57}{2})

Step-by-step explanation:

Hi there!

We are given the coordinates (26, 56) and (26, 1)

We want to find the midpoint of these two points

The midpoint can be found using the formula (\frac{x_1 + x_2}{2} , \frac{y_1 + y_2}{2}), where (x_1, y_1) & (x_2, y_2) are points

We have 2 points, which is what we need to find the midpoint, but let's label the values of the points to avoid confusion and mistakes when actually calculating

x_1=26\\y_1=56\\x_2=26\\y_2=1

Now substitute these values into the formula.

(\frac{x_1 + x_2}{2} , \frac{y_1 + y_2}{2})

(\frac{26 + 26}{2} , \frac{56+ 1}{2})

Add the numbers together

(\frac{52}{2} , \frac{57}{2})

Divide

(26, \frac{57}{2})

Hope this helps!
