❄ Hi there,

keeping in mind that the sum of complementary angles is 90°,

set up an equation, letting \angle2  be x  –

\triangleright \ \sf{\angle1+x=90}                 {and we know that \boxed{\angle1=45}}

\triangleright \ \sf{45+x=90}

\triangleright \ \sf{x=90-45}

\triangleright \ \sf{x=45}

\triangleright \ \sf{\angle2=45\textdegree}

      __________

Keeping in mind that a right angle is 90°,

set up an equation, letting \angle1 be x:

\triangleright \ \sf{x+\angle2=90}                       {and we know that \boxed{\angle2=63}}

\triangleright \ \sf{x+63=90}

\triangleright \ \sf{x=27}

\triangleright \ \sf{\angle1=47\textdegree}

Geometry question, please help me
vesna_86 [32]
Hi there!

First, let's find the proportion of the radius' and set it equal to the proportion of the heights:
12/10 = 30/25

Next, we'll cross multiply. If the numbers are the same, then the solids are similar.
300 = 300

The solids are similar! The scale factor from the larger solid to the smaller solid is 6/5 or 1.2. The scale factor from the smaller solid to the larger solid is 5/6.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
