We have to construct a triangle DEF with EF = 7 cm. It is given that we have to make an angle of 50⁰ at E and at F.
Steps to make a triangle DEF:
Step 1: Draw a line segment EF equal to 7 cm, using a ruler.
Step 2: Put the center of the protractor on the one end of the line segment that is at E and make the given angle that is 50⁰.
Step 3: Make the angle of 50⁰ at F by using protractor.
Step 4: Extend the line from E and F in the direction of 50⁰. After extending the line segments, we get an intersection point, name that point D..
Step 5: The point D, is made from the intersection of the line segment from E and F.
Step 6: Hence, triangle DEF is constructed.

Answer:
Triangle E
Step-by-step explanation:
(x,y) --> (y,-x)
Answer:
6x+20 or 2(3x+10)
Step-by-step explanation:
Six friends went to a basketball game and four people paid $5 extra for a t-shirt. To find the total cost, multiply 6 by x and 4 by 5 this add them together:
6*x+4*5
6x+20, If needed you can factor this expression to:
2(3x+10)
Answer:
5 + 8x = 2
Step-by-step explanation:
We have that
the expressions is <span>∑ i=1 to 5 (4i)
for i=1-----------> (4*1)=4
</span>for i=2-----------> (4*2)=8
for i=3-----------> (4*3)=12
for i=4-----------> (4*4)=16
for i=5-----------> (4*5)=20
∑ i=1 to 5 (4i)=[4+8+12+16+20]=60
the answer is 60
