Answer:
B. 75°
Step-by-step explanation:
When lines that are parallel are crossed by a transversal , angles in matching corners are equal and called corresponding angles
To get the value of the angle;
180°-105°= 75°.................sum of angles on a straight line
This angle corresponds to angle y because of the parallel lines DE and XY
Answer:
Perimeter = 2 ( l + w )
if u r given for rectangle thats the formula
Answer: a=14
Step-by-step explanation:
Equation: 5=1/2a-2
His average is 4.2 seconds. hope it helps
ill try my best
Add the two angles you already know (for example, 50 and 45), then, with the sum of the two angles (95), subtract it from 180 (180-95) and there's your answer. How do I find the third angle of a triangle if the two known angles are 35 and 40?
The measure of any exterior angle of a triangle is equal to the sum of the measures of its two interior opposite angles. The sum of the three angles of a triangle is 180°. ... The sum of the lengths of any two sides of a triangle is always greater than the length of the third side.
all i got (:
