Answer:
60 degrees
Step-by-step explanation:
This is a complementary angle, so the equation to use is 30+x=90.
To find out what <em>x</em> is, we have to use the Subtraction Property of Equality.
30+<em>x</em>=90
-30 -30
<em>x</em>=60
Answer:
The method you would use to prove the two Triangles is
AAS
Step-by-step explanation:
Given:
First label the figure
∠ A =∠ D = 60°
∠ B =∠ E = 40°
BC = EC = 10
To Prove:
Δ ABC ≅ ΔDEC
Proof:
In Δ and Δ
∠ A ≅ ∠ D ……….{Given measure of each angle is 60°}
∠ B ≅ ∠ E ……….{Given measure of each angle is 40°}
BC ≅ EC ………...{Given measure of each side is 10 units}
∴ Δ ABC ≅ Δ DEC ….{By Angle-Angle-Side test}
Answer:
You can solve this by substitution method
substitute the value of Y from 2nd equation in the first thet will give you the value of X and once your find the value of X you can substitute that value in any of the equation and get the answer
