Angles In Triangles ​
Elden [556K]

Answer:

It's a isosceles triangle, i am not saying its clearly implied in the diagram with the red lines.... Which state that both the sides have same length

Hence if on ne side makes 55 with the base therefore the side with same length will make 55 with the base too

Hence its

55+55+x=180

X= 180-55-55

X= 70 degree

Therefore x is 70 degree

The diameter of each wheel of a bicycle is 27 inches. If you are traveling at a speed of 20 miles per hour on this bicycle, thro
klasskru [66]
Notice, you've got a diameter in inches
and a linear velocity in miles
thus, you'd need to convert first

\bf v=rw\implies \cfrac{v}{r}=w\qquad 
\begin{cases}
v=\textit{linear speed}\\
r=radius\\
w=\textit{angular speed}\\
 --------------\\
v=20\frac{mi}{h}\\
r=\frac{diameter}{2}=\frac{27}{2}
\end{cases}
\\\\
\textit{now, converting 20miles to inches}
\\\\
\cfrac{20mi}{h}\cdot \cfrac{5280ft}{mi}\cdot \cfrac{12in}{ft}\implies \cfrac{20\cdot 5280\cdot 12\ in}{h}\impliedby v
\\\\\\
\cfrac{1267200\frac{in}{h}}{\frac{27}{2}in}=w

now, whatever that is, you'll need to divide it by a revolution, recall, a revolution is 2\pi
thus \bf \cfrac{\qquad \boxed{\cfrac{1267200\frac{in}{h}}{\frac{27}{2}in}}\qquad }{2\pi }=revolutions

A farmer has a rectangle field with a perimeter of 5.4 miles and a length of 2.3 miles. Find the width of the field. The width o
Alja [10]

Answer:

Step-by-step explanation:

perimeter = 2*(length + width)

53 m = 2*(2.3 m +w) . . . . an equation to find the width, w

26.5 m = 2.3 m +w . . . . . divide by 2

24.2 m = w . . . . . . . . . . . subtract 2.3 m

The width of the rectangle is 24.2 m

hope it helps

Question : 3/4+ 0.6 = ? 1.15 1.35 1.45 or 1.05
Artyom0805 [142]

we have

\frac{3}{4} +0.6

we know that

\frac{3}{4}=0.75

and

0.75=0.40+0.35

substitute in the expression

0.40+0.35 +0.6

(0.40+0.60)+0.35

(1.00)+0.35=1.35

therefore

<u>the answer is</u>

1.35
