ANSWER
C) Triangle
EXPLANATION
Solving a triangle is the process of calculating unknown side lengths or angle measures of a triangle if certain of the side lengths and/or angle measures are known.
We use the sine rule and cosine rule to find the missing sides and angles.
If the triangle has a right angle, then this is a special case, where we can use the trigonometric ratios and the Pythagoras theorem to find the unknown angles and sides.
Answer:
21/41
Step-by-step explanation:
Find the total number of students
6+7+2+3+6+8+4+5=41
Then find the students that do not study chemistry
6+7+2+5 = 20
P( not study chemistry) = do not study chem)/total
=21/41
You know that two expressions are equivalent when if you substitute in your values and simply the expressions, they have the same answer.
To find the area of a triangle uses the equation base*height/2. For this equation, we have 26 * h/2 = 195. This means that 26 * h = 195 * 2.
26 * 15 = 390, so your answer is 15 cm.
Answer:
75.062c
Step-by-step explanation:
To find the missing side use pythagorean theorem
So 
Solve for b, b= 6.021
To find the area use 
bh
So (6.021+19)(6)= area
And you get 75.062
