Answer:
Step-by-step explanation:
The given postulate If two lines intersect, then they intersect in exactly one point is true because whenever the two lines intersect they intersect at one point only and we know that a postulate is a statement that we accept without proof.
The given theorem If two distinct planes intersect, then they intersect in exactly one line is true as theorem is a statement that has been proved and it has been proved that if two distinct planes intersect, then they intersect in exactly one line.
The figures are drawn to prove them.
Answer: 60
Step-by-step explanation:
You have to use Pythagorean Theorem because the other side is not listed of the triangle
Pythagorean Theorem: a² + b² = c²
a² + 20² = 25²
a² + 400 = 625
625-400 = a²
a² = 225
Find the square root of 225 to find the missing length
= 15 (this is the missing length for QS
To find the perimeter, add all the sides...
15 + 20 +25 = 60
The y-intercept coordinate is at the point (0, 17)
<h3>Properties of functions</h3>Given the following function expressed as:
The x-intercept is the point where y = 0
Hence the x-intercept is (43/9, 0)
The y-intercept is the point where x = 0
The y-intercept coordinate is at the point (0, 17)
