Since we are given the lengths of 2 sides with the angle in
between, therefore by cosine law we can only construct 1 triangle from this. By
stating the angle in between, this constricts the possible number of triangles
that can be formed into 1.
By calculation, the length of the 3rd side is
calculated using cosine law:
c^2 = a^2 + b^2 – 2abcosθ
c^2 = 10^2 + 8^2 – 2(10)(8)cos40
c = 6.44 cm
ANSWER:
1 triangle
Answer:
2.08
Step-by-step explanation:
Hey!
----------------------------------------------------------------
We Know:
m∠AED = 34°
m∠EAD = 112°
----------------------------------------------------------------
Solution:
You notice 4 small triangles in both triangles. That shows that both triangles are the same.
The angles are the same for m∠BDC and m∠AED.
The angles are the same for m∠ADB and m∠EAD
----------------------------------------------------------------
Angles:
m∠BDC = 34°
m∠ADB = 112°
----------------------------------------------------------------
Congruent Angles:
m∠AED ≡ m∠BDC
m∠EAD ≡ m∠ADB
----------------------------------------------------------------
Hope This Helped! Good Luck!
I believe the fourth one is the answer.
Answer:
5 = term
sum = +
product = x or * (times)
4 = coefficent
quotient = division symbol
factor = 2
