Answer: The ratio of the perimeter = 7/4
The ratio of the area = 28/21
Took me alot of time ;p pls mark as brainliest! :)
What is the second question? Don’t seem to understand what you’re asking
But the first is
(2sinx-1)(Sinx-1)
Treat it the sinx as you would with normal factorising equations with x. If it helps you, you could always substitute the sinx as a U, and then change it back to sinx once you have factorised it
Answer:
Step-by-step explanation:
c.d. d=11-18=4-11=-7
y=18+(n-1)(-7)
or y=18-7n+7
or y=25-7n
n=1,2,3, ...
Given that there is no any option to choose I am going to help you according to the concepts of
Congruent Triangles. Two triangles are congruent if and only if:
1. They have:exactly the same three sides
2. exactly the same three angles.
<span>There are five ways to find if two triangles are congruent but in this problem we will use only two.
First Answer:<u>ASA criterion:</u> </span><em>A</em><span><em>ngle, side, angle</em>. This means that we have two triangles where we know two angles and the included side are equal.</span>
So:
If ∠BAC = ∠DEF and
<em>Then ΔABC and ΔEFD are congruent by ASA criterion.</em>
Second answer:<u>SAS criterion:</u> <em>S</em><span><em>ide, angle, side</em>. This means that we have two triangles where we know two sides and the included angle are equal.
</span>
<em>Then ΔABC and ΔEFD are congruent by SAS criterion.</em>
