B, there are two sections that say 1, and there are less sections then the other one with two ones
Answer:
Rate of change = 9
Step-by-step explanation:
m= (y2 - y1) / (x2 - x1)
= (25 - 7) / (4 - 2)
= 18 / 2
= 9
Answer: 6
Step-by-step explanation:
From the question, a base angle of isosceles triangle is 30°.We are also informed that one of the legs is 12. The altitude is opposite to the angle having a measure of 30°. The hypoteneous in the right angled triangle which is formed by drawing the altitude is 12. This will be calculated as:
Sin = opposite/hypotenuse
Sin 30°=length of the altitude/12
Note that sin 30° = 0.5
0.5 = length of the altitude/12
length of the altitude = 12 × 0.5
Hence, length of altitude = 6
Answer:
There are 29 triangles when you count them all including non obvious ones.
