3b+2(b-1) = 8
3b+2b-2 = 8
5b = 8+2
5b = 10
b = 2
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:
Distance of point P(3,0) from x axis is zero as this point lies on x axis.
distance of point Q is 3.
Distance of point R is 4.
Distance of point S is 3.
Step-by-step explanation:
Point P already lies on x axis as its y coordinate is zero so its distance from x axis is zero
distance of points Q , R and S is the absolute value of their y coordinates that is 3 , 4 and 3 respectively.

Maybe you can study it or figure out a trick. I usually study with my sibling, but if you don't have any, friends or other family. I am sure they won't mind. Also, maybe making flashcards, those work well.
Also, you can print out worksheets and make your brain remember. PRACTICE!
