Hello!
The angle is a right angle, which measures 90°.
3x + x = 4x
Angle = 4x + 10 = 90
Switch that around
90 - 10 = 4x
90 - 10 = 80
80 = 4x
Divide by 4

Answer:
an isosceles right triangle
Step-by-step explanation:
The square of the length of a side can be found from the distance formula:
d^2 = (x2-x1)^2 +(y2-y1)^2
The square of the length of WX is ...
WX^2 = (-3-(-10))^2 +(-1-4)^2 = 49+25 = 74
The square of the length of XY is ...
XY^2 = (-5-(-3))^2 +(11-(-1))^2 = 4 +144 = 148
The square of the length of YW is ...
YW^2 = (-10-(-5))^2 +(4 -11)^2 = 25 +49 = 74
The sum of the squares of the short sides is equal to the square of the long side, so this is a right triangle. The squares of the short sides are equal, so this is an isosceles right triangle.
Answer:
the answer is (d) 57°
Step-by-step explanation:
since it's a straight angle it equals to 180°
you divide 180° from 123°

Answer:
<h3>k = 10</h3>
Step-by-step explanation:
Given the equation;

We are to find the value of k.
Cross multiply;

Divide both sides by 10

Hence the value of k is 10
