All i know is that the first one is an integer i think.
Answer:
(2n + k) - 7
Step-by-step explanation:
1. Let ''a number'' be presented as n
2. ''twice a number'' → 2
n
3. ''twice a number and k'' → 2n + k
4. 7 less than twice a number → (2h + k) - 7
Google it!
alright so first ur trying to find adjacent so use cos which is adjacent/hypotenuse you know the angle of c is 90 because it is a right angle
so it gonna be
cos(90)= AC/5
5*cos(90)= AC
5*0=AC
side AC = 0
Answer:
Side AC is congruent to side DF
Step-by-step explanation:
We are given that
Side AB=5 cm
BC=6 cm
Side DE=5 cm
Side EF= 6cm
We have to find an additional information would need to prove that
by SSS.
When two triangles are congruent by SSS it means three sides of one triangle are congruent to corresponding sides of other triangle.
We have in triangle ABC and triangle DEF



Then ,
DEF
Reason: SSS postulates
Answer: Side AC is congruent to side DF
There are 1 rectangle and 2 triangles.
The area of the rectangle is 5 x 7 =35
The are of the triangle is 7 x 2 = 14(1/2) = 7
There are 2 triangles, so 7 x 2 = 14
14 + 35 = 49
49 is your answer
hope this helps
