13cm because c is the hypotenuse .with formulae right angle triangle of 5^2+12^2=13
Answer:
<em>B. Triangles A and C</em>
Step-by-step explanation:
Let's find the missing angle of all Triangles:
Triangle A: 180-110-30=40°
Triangle B: 180-30-45=105°
Triangle C: 180-110-40=30°
All triangle angles in numerical order:
ΔA: 30, 40, 110
ΔB: 30, 45, 105
ΔC: 30, 40, 110
We see that only ΔA and ΔC are congruent with the same angle sizes.
Answer
-sqrt(18)<x<sqrt(18)
Step-by-step explanation:
- Factorise:(x-sqrt(18))(x+sqrt(18))<0
- Critical values:-sqrt18 and sqrt18
- Use number line or graphical method
Answer:
1 / 36
Step-by-step explanation:
A roll of 2 fair dice :
Total number of possible outcomes = n² ; n = number of faces in a dice = 6² = 36
Probability = required outcome / Total possible outcomes
Required outcome = total less than 3 = 1 (from sample space provided)
Hence,
P(total less than 3) = 1/36
