Question

How many degrees are there in (i) three right angles ?
(ii) 4/9 right-angle ?​

Answer 1

Answer:

i) Number of degrees in three right angles = $270^{0}$

 ii) Number of degrees in $\frac{4}{9}$ right angle = $40^{0}$

Step-by-step explanation:

• Here, in this example, we have to find that :
• How many degrees are there in

       (i) three right angles ?

       (ii) 4/9 right-angle ?

• Solution :

• As we know that the measure of a right angle is $90^{0}$.
• Now,

      i) Number of degrees in three right angles = $3*90^{0}$

                                                                    = $270^{0}$

 

      ii) Number of degrees in $\frac{4}{9}$ right angle = $\frac{4}{9} *90$

                                                             = $4*10$

                                                             = $40^{0}$  

• ∴ i) Number of degrees in three right angles = $270^{0}$
•  ii) Number of degrees in $\frac{4}{9}$ right angle = $40^{0}$

Answer 2

Answer:

270 degrees are there in three right angles.

40 degrees are there in 4 by 9 right angle.
