Cut up the shape into triangles, rectangles or trapezoids and calculate the individual areas.

Here,

Top triangle = (1*7)/2 = 3.5

Left triangle = (4*5)/2 = 10

Right trapezoid = (4+5)*3/2=13.5

So total area = 3.5+10+13.5=27

Find z. Write your answer in simplest radical form.

lara [203]

$\qquad \qquad\huge \underline{\boxed{\sf Answer}}$

Let's solve ~

The given triangle is a right angled Triangle, so we can apply Trigonometric relations to find the required result ;

That is :

$\qquad \sf \dashrightarrow \: \sin(30 \degree) = { \dfrac{z}{2 \sqrt{2} } }$

$\qquad \sf \dashrightarrow \: \dfrac{1}{2} = \dfrac{z}{2 \sqrt{2} }$

$\qquad \sf \dashrightarrow \: z = \dfrac{2 \sqrt{2} }{2}$

$\qquad \sf \dashrightarrow \: z = \sqrt{2}$

So, the value of z is $\sqrt{}{2}$

julsineya [31]

Answer:

56/45 or 1 11/45

Step-by-step explanation:

change to improper fractions and multiply the first by the reciprocal of the second

$\frac{14}{3}$ ÷ $\frac{15}{4}$ = $\frac{14}{3}$ · $\frac{4}{15}$ = $\frac{56}{45}$

45 goes into 56 1 time with a remainder of 11
