Help me solve (b) in this quadrilateral
Savatey [412]

Answer:

b = 87°

Step-by-step explanation:

In order to answer this question, we need to utilise an important angle fact which is <em>angles in a quadrilateral add up to 360° </em>

Using the information we can set up an equation to find the value of b

→ Form equation

63 + 140 + 70 + b = 360

→ Simplify

273 + b = 360

→ Minus 273 from both sides isolate b

b = 87°

Find the 22nd term of the sequence described by the<br> explicit formula:<br> f(n) = 8 + 3(n - 1)
kari74 [83]
<h3><u>Answer:</u></h3>

\boxed{\boxed{\pink{\bf \leadsto The \ 22nd \ term \ is \ 71. }}}

<h3><u>Step-by-step explanation:</u></h3>

Given that the nth term of the Arthemetic Sequence is given by :-

\implies f(n) = 8 + 3(n-1)

And we need to find the 22nd term .

So in place of n substitute 22 .

\bf\implies f(n) = 8 + 3(n-1) \\\\\bf\implies f_{22} = 8 + 3(22-1) \\\\\bf\implies f_{22} = 8 + 3\times 21 \\\\\bf\implies f_{22} = 8 + 63 \\\\\bf\boxed{\bf\implies f_{22} = 71 }

<h3><u>Hence </u><u>the</u><u> </u><u>2</u><u>2</u><u>n</u><u>d</u><u> </u><u>term</u><u> </u><u>is</u><u> </u><u>7</u><u>1</u><u> </u><u>.</u></h3>
