Answer:

{\huge{\pink{\underline{\underline{Solution:}}}}}

As we know,sum of angles on a straight line is 180 degree..

(5z-4)+90+39=180

=>5z-4+90+39=180

=>5z-4+129=180

=>5z+125=180

=>5z=180-125

=>z=55÷5

Hence,the value of z=11 degree

Can anyone tell the answer for the 3rd qouestion
N76 [4]

Answer:

Your first 2 questions are correctly answered.

I think the answer to the third question is NO.

Step-by-step explanation:

You can see that the sides with 3 and 4 are adjacent, which means they cannot possibly be opposite. For a valid dice, they should be opposite because they add up to 7. Hence this net is not valid.

50 POINTS: Please help thank you so much!! (Image attached) The polygons are similar. Find the values of the variables.
BlackZzzverrR [31]

Step-by-step explanation:

9 + y^2 = 49

y^2 = 40

y = √40 = 2√10

4.5/3 = 2√10/5x

22.5x = (3) 2√10

22.5x = 6√10

x = 6√10/22.5 = 3√10/11.5

A 30-m tall building casts a shadow. The distance from the top of the building to the tip of the shadow is 32 m. Find the length
zepelin [54]

Answer: 11.1 m

Step-by-step explanation:

This can be solved by the Pythagorean theorem where;

c² = a² + b²

c is the hypotenuse which is the distance from the top of the building to the tip of the shadow.

a is the height

c is the length

32² = 30² + b²

b² = 32² - 30²

b² = 1,024 - 900

b² = 124

b = √124

b = 11.1 m
