Answer: H = 8 cm
Step-by-step explanation: Since a triangle's area is b times h/2, we know that two times 48 is 96, therefore we can opposite the equation so 12 is the base times the height (8 cm) is 96 divided by 2, there's your answer.
Add the zeros on to 7.5 to which you would move the decimal and it should be like this 750.0 or 750
Answer:
1. Given
2, Exterior sides on opposite rays
3. Definition of supplementary angles
4. If lines are ||, corresponding angles are equal
5. Substitution
Step-by-step explanation:
For the first one, it is given as shown in the problem. Also in the figure you can see that line s is parallel to line t.
2. ∠5 and ∠7 are adjacent, they share a common side. Their non-common side are rays that go in a direction opposite of each other. Also you can see that they form a straight line, which means that they are supplementary.
3. Supplementary angles simply put are angles that sum up to 180°. You know this for sure because of proof 2, specifically the part that they form a straight line. The measure of a straight line is 180°.
4. Corresponding angles are congruent. These are angles that have the same relative position when a line is intersected by parallel lines. You have other example in the figure like ∠2 and ∠6; ∠3 and ∠7.
5. This is substitution because ∠1 substituted ∠5 in this case. Since ∠1 is equal to ∠5, then it can substitute it in the equation given in step 3. This means that ∠1 and ∠7 are supplementary as well.
Answer: B) is the right answer→the distance between points a and b is equal to the distance between points b and c.
Step-by-step explanation:
As Kerry drew a number line starting at 0, point a, and ending at 1, point c and halfway between points a and c, he added point b.
.⇒ab=1/2 of ac and bc= 1/2 of ac or b is the mid point of line segment ac.
⇒ ab=bc(∵things which are equal to the same thing are equal to one another....→Euclid's first postulate)
Therefore, option B) the distance between points a and b is equal to the distance between points b and c is correct.
