What is the answer to the following: (reference the photo for answer)

Mathematics
1 answer:
Artyom0805 [142]3 years ago
5 0

Answer:

9

Step-by-step explanation:

To calculate c from the first right angle triangle,

C2 = 36 + 16

C = sqrt(52)

To calculate a from the bigger right angle triangle,

B2 + 52 = (a + 4)2

B2 - a2 = -36 + 8a

A2 + 36 = B2

Solving both by elimination,

A = 72/8

=9

Answer:

-7  \frac{1}{2}

Step-by-step explanation:

\frac{6 {x}^{ - 1}  {y}^{ \frac{7}{2} } }{ \sqrt{16 {x}^{2} }  {y}^{2} } \\  \\  =   \frac{6 {x}^{ - 1}  {y}^{ \frac{7}{2} } }{ \sqrt{(4 {x} {y})^{2} }}\\  \\  =  \frac{6 {x}^{ - 1}  {y}^{ \frac{7}{2} } }{ {4 {x} {y}}}\\  \\  =   \frac{6}{4}  {x }^{ - 1 - 1}  {y}^{ \frac{7}{2} - 1 }  \\  \\   =   \frac{3}{2}  {x }^{ - 2}  {y}^{ \frac{5}{2} }  \\  \\ equating \: it \: with \:  \\ a {x}^{b}  {y}^{c}  \\  \\  \implies \\ a =  \frac{3}{2}  \\  \\ b =  - 2 \\  \\ c =  \frac{5}{2}  \\  \\ abc =  \frac{3}{2}  \times ( - 2) \times  \frac{5}{2}  \\  \\  =  -  \frac{15}{2}   \\  \\  =- 7 \frac{1}{2}  \\

Someone, please help! Thank you!
Setler79 [48]

Answer:

324°

Step-by-step explanation:

Totak angles in a 7 sided polygon = 900°

Side A = 3

Side B = 1

Side C = 4

Side D = 1

Side E = 5

Side F = 9

Side G = 2

Total = 25

The largest angle has the largest ratio which is side F

Angle in side F = Ratio of side F / total ratio × 900°

= 9/25 × 900°

= 0.36 × 900°

= 324°

The largest angle = 324°

The smallest angles are angles with the lowest ratio which are side B and side D

Angle in side B = Ratio of side F / total ratio × 900°

= 1/25 × 900°

= 0.04 × 900°

= 36°

The smallest angles are angles 36°
