The angle is equal, set x+40 = 60 solve for x, which is 20
Answer:
Therefore the required probability is
Step-by-step explanation:
The probability of success is
The number of trial = 4
X= the items survive out of 4
p =the probability of success and q = the probability failure.
p= and
Therefore the required probability is
Angle 1 = 30°
Angle 2 = 90°
⇒ Angle 3 = 60°
So, it's right triangle. We can set the length of one side and get all other sides.
So, we have 1 triangle. If there are 2 or more triangles with the same data, all the triangles will be congruent because of : <span>Two triangles are </span><span>congruent if </span>"<span>ASA: Two interior angles and the included side in a triangle have the same measure and length, respectively, as those in the other triangle</span><span>.</span>"
