How to split the numbers to add

Mathematics
2 answers:
iris [78.8K]3 years ago
8 0

This sheet presumes making number into 10 helps make adding easier

2.  8 + 5 =

    10 +  3 = 13  we get 3 by taking 2 from 5 and giving it to the 8 to get 10


3.  8 + 6 =

     10 + 4  = 14     take 2 from 6 to give to 8 to make 10


I suspect the purpose of this is to promote mental math

Answer:

I'm going to explain this by doing number 2.

Step-by-step explanation:

Okay, so 8 is 2 away from 10. So we subtract 2 from 5, leaving 3. We add the 2 to the 8, making 10. Now, we add the other 3. 10+3=13. 8+5=13.

Answer: Option A

\theta=tan^{-1}(\frac{8}{6})

Step-by-step explanation:

We can model the situation by means of a right triangle.

Where the  angle \theta is the angle that you make with the top of the TV.

Then the horizontal distance of 6 feet is the adjacent side and the vertical distance of 8 feet is the opposite side to the angle the.

By definition of the tan(\theta) function we know that:

tan(\theta)=\frac{opposite}{adjacent}

Therefore:

tan^{-1}(\frac{8}{6})=\theta

\theta=tan^{-1}(\frac{8}{6})

Plz solve this problem of trigonometry<br>i am an aakashian​
makkiz [27]

Step-by-step explanation:

\bf L.H.S = \tt \dfrac{sec\: \theta + tan \:  \theta - 1}{tan \:  \theta - sec \:  \theta + 1}  \\  \\

:  \implies \tt \dfrac{\frac{1}{cos  \: \theta}  +  \frac{sin \:  \theta}{cos \: \theta}  - 1}{  \frac{sin \:  \theta}{cos \:  \theta} -  \frac{1}{cos \:  \theta} + 1   } \:  =   \dfrac{1 + sin \:  \theta - cos \:  \theta}{sin \: \theta + cos \:  \theta} \\  \\

: \implies \tt\dfrac{ sin \:  \theta - (cos \:  \theta - 1)}{sin \: \theta + (cos \:  \theta - 1)} \:  \times  \: \dfrac{ sin \:  \theta - (cos \:  \theta - 1)}{sin \: \theta  -  (cos \:  \theta - 1)} \\  \\

: \implies \tt\dfrac{ sin^{2}  \:  \theta  + cos^{2}  \:  \theta  + 1 - 2  \: cos \:  \theta  - 2  \: sin \:  \theta \: (cos \:  \theta - 1)}{sin^{2}  \: \theta  -  (cos \:  \theta - 1)^{2} } \\  \\

: \implies \tt\dfrac{1 + 1 - 2 \:  cos \:  \theta - 2 \: sin \:  \theta  \: cos \:  \theta + 2 \: sin \: \theta}{sin^{2} \: \theta + cos^{2} \: \theta - 1 + 2 \: cos \:  \theta } \\  \\

: \implies \tt\dfrac{2 - 2 \:  cos \:  \theta - 2 \: sin \:  \theta  \: cos \:  \theta + 2 \: sin \: \theta}{sin^{2} \: \theta + cos^{2} \: \theta  - sin^{2} \:  \theta - cos^{2}   \:  \theta  + 2 \: cos \:  \theta } \\  \\

: \implies \tt\dfrac{2 (1 - \:  cos \:  \theta )- 2 \: sin \:  \theta  (1 - \: cos \:  \theta)}{ 2 \: cos \: \theta - 2 \: cos^{2}   \:  \theta} \\  \\

: \implies \tt\dfrac{(2  +  2 \:  sin \:  \theta)  \:  \cancel{(1 -  cos\:  \theta)}}{2 \: cos \:  \theta  \:  \cancel{(1 - cos \:  \theta)}} \:  =  \:  \dfrac{1 + sin \:  \theta}{cos \: \theta}  \\  \\

: \implies\tt\dfrac{1 + sin \:  \theta}{cos \: \theta}  \:  \times  \: \dfrac{1  -  sin \:  \theta}{1 - sin \: \theta} \\  \\

:  \implies\tt\dfrac{1 + sin^{2}  \:  \theta}{cos \: (1 - sin \: \theta)} \\  \\

:  \implies\tt\dfrac{cos^{2}  \:  \theta}{cos \: \theta (1 - sin \: \theta)} \\  \\

:  \implies\tt\dfrac{cos \:  \theta}{1 - sin \: \theta}  \:  = \:  \bf{ R.H.S}\\  \\
