Answer:

Step-by-step explanation:

since the inside of a triangle is equal to 180

180-42-73=65

65/5=13 so 13 should be the answer.

Sum of the interior angles of a triangle= 180°

Therefore, 42°+ 73°+5a= 180°

=> 115°+5a = 180°

=> 5a= 180- 115°

=> 5a = 65°

=> a = 65°/5

=> a= 13°

Which sequence follows the rule 2n + 6, where n represents the position of a term in a sequence? 6, 8, 12, 18, . . . 6, 12, 18,

melamori03 [73]

ANSWER

8, 10, 12, 14, . . .

EXPLANATION

The given rule for the sequence is :

f(n)=2n+6

The domain for a sequence is the set of natural numbers.

When n=1,

f(1)=2(1)+6=8

When n=2,

f(2)=2(2)+6=10

When n=3,

f(3)=2(3)+6=12

When n=4,

f(4)=2(4)+6=14

Therefore the sequence that follows the given rule is

8, 10, 12, 14, . . .

Solve the following problems. Choose the letter of the correct answer. (Show your complete solutions.)

i didnt understand the question because of my English sorry

we all know that the total of degrees is 180 so 70+70=140

180-140=40

so the answer is 40

we have a figure with 4 angle so the total of degrees is 360 so the answer is 126

the answer most be 50 becuse we have a Special degree witch always equal 90 if we have recatngle so

x+40=90

X=50 the answer and if you want to try again choose the second one

2x-10=90

2x=100

X=50 same answe you see

in this quastion i searched and find alot of answers any way

its should be 7 or 3 but the correct answer in my opinion its 7

its shows in the picture i sent hopefully its helpful to you i will try to translate the first quastion and sent it to you
