It's 130, any quadrilateral's angles add up to 360 and those numbers add up to 230, 360-230 = 130
Answer: Walk through writing a general formula for the midpoint between two points. ... I believe you would simply find the differences in x and y from the midpoint to the one ... How would you solve a problem in which you do not know point B but are given ... the line y=x and the curve y=4x-x^2 intersect at the point p and q.
Step-by-step explanation:
Answer:


Step-by-step explanation:
Given
Shape: Rectangle


Required
Determine the dimensions
The perimeter of a rectangle is:

Substitute 120 for Perimeter

Divide both sides by 2

Substitute 3 * Height for Base



Divide both sides by 4


Substitute 15 for Height in 


Mass by grams = mass by kilograms *1000
so , mass by grams = 15.6 *1000 = 15600 grams
Step-by-step explanation:
To prove that 3 + 2√5 is an irrational number, we will use the contradiction method.
Let us assume that 3 + 2√5 is a rational number with p and q as co-prime integers and q ≠ 0
⇒ 3 + 2√5 = p/ q
⇒ 2√5 = p/ q - 3
⇒ √5 = (p - 3q ) / 2q
⇒ (p - 3q ) / 2 q is a rational number.
However, √5 is an irrational number
This leads to a contradiction that 3 + 2√5 is a rational number.
