Answer:
C. 2/3
Step-by-step explanation:
To find the slope of a line from two points, use this formula.
The variable 'm' means slope in algebra.
y² means the second y-coordinate and y^1 means the first y-coordinate.
Based on the previous definition, it should be easy to figure out what x² and x^1 mean.
Therefore, the slope of the line passing through the points (2,4) and (5,6) is 2/3.
Let me know if you have any questions.
Answer:
2. C) 21.2 yd 3. B) angle IQL 4. B) 55 degree
Step-by-step explanation:
2. The area of an equilateral triangle is given by,
A = ------(1) where a = length of each side.
Here, a = 7 yd
so , putting a = 7 yd in (1) , we get,
A = sq. yd.
sq. yd.
3. B) angle IQL
4. Let, the centre of the circle be at O,
then, ∠DOB = 105° and ∠BOC = 145° (given)
so, ∠OBD =
=
= 37.5° [since the sum of three angles of a triangle is 180° and OB and OD are two radii of the same circle]
and, similarly, ∠OBC =
=
= 17.5° [since the sum of three angles of a triangle is 180° and OB and OC are two radii of the same circle]
so, ∠CBD = ∠OBD + ∠OBC
= 37.5° + 17.5°
= 55°
