Answer:

4z+2(square)2z=2(square)6

Step-by-step explanation:

4((z+3(z-1)))=36

4(z^2-z+3((z-3)))=36

4(z^2-z+3z-3)=36

4((z^2+(-z+3z)-3))=36

4(z^2+2z-3)=36

4z^2+8z-12=36

4z^2+8z=24

((4(square)z^2))+(square)8z=(square)24

4z+2(square)2z=2(square)6

Answer:

Step-by-step explanation:

4[z+3(z-1)]=36

z+3(z-1)=36/4

z+3z-3=9

4z-3=9

4z=9+3

4z=12

z=12/4

z=3

The ratio of the measures of two complementary angles is 7:8. What is the measure of the smaller angle

patriot [66]

Answer: 42°

Step-by-step explanation:

Complimentary angles are angles sum up to make 90°

From the ratio given 7:8,

Add the ratios together and find the smaller angle as follows

7 + 8 = 15

Therefore,

⁷/₁₅ x 90 = 42°

The smaller angle is 42°

Use the fact that the length of an arc intercepted by an angle is proportional to the radius to find the arc length given that r

Komok [63]

Answer:

The required length is 37.68 cm

Step-by-step explanation:

We have given the radius of which is 3 cm and $\theta$ which is $\pi\cdot 4$

We will use $\pi=3.14$

We know the formula for length of arc which is:

length of arc=radius x angle

We will substitute the values given we will get:

$length=3(3.14)(4)$

$length=37.68$

Hence, the required length is 37.68 cm
