Answer:
In a right angle triangle, one of the angles is 90°. It is given that one of the acute angled of the right angled triangle is 50°. We know that the sum of the measures of all the angles of a triangle is 180°. Now, let the third angle be x.
Answer:
Step-by-step explanation:
Note that in this diagram, point A represents point X, point B represents point Y, and point C represents point Z.
From the diagram, it appears as if 
. To determine if this is the case, we can find the slopes of both segments.
Since these slopes are negative reciprocals, we know that they are perpendicular.
This means we can use the formula 
, where b is the base (XY) and h is the height (XZ).
- Note these are interchangeable.
Using the distance formula,
This means the area is 
Answer:
∠ABC= 40° ∠CBD=60° ∠EBD=80°
Step-by-step explanation:
Step 1: 2x+3x+4x=180
A straight line is 180 degree's, and to get the value of the different angles, you have to add the three angle measures.
Step 2: 9x=180
Combine like terms
Step 3: x=20
Divide/ Isolate the variable
Step 4: 2(20)=40 3(20)=60 4(20)=80
Plug the answer back in
