You can use this to help you. label the triangle like the picture and use the equations. I hope this helps.
4 over 12 times 8 over 20
= 4/12 * 8/20 ....( 4/12 = 1/3; 8/20 = 2/5)
=1/3 * 2/5
=2/15
Answer:
x = 25°
Step-by-step explanation:
2x-10°+2x-10°+100°=180°[sum of angles in a triangle ]
4x+80°=180°
4x=100°
x=25°
Answer:
BD is half of the answer BF is
Step-by-step explanation:
BD is only half of BF so find the answer for BF and then divide by @ and you have your answer.
Answer with explanation:
In Δ ABC and ΔD BC
∠A=∠D-------Given
∠ABC=∠DCB-------Each being 90° given in the Diagram.
Side, BC is Common.
⇒⇒Δ ABC ≅ ΔD BC-------[AAS]
When two triangles are congruent , their areas are equal.
So, Area(ABC)=Area (DCB)
Option B :⇒ A AS
