Answer:
x ≈ 2.3 cm
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos55° = 
= 
( multiply both sides by 4 )
4 × cos55° = x , thus
x ≈ 2.3 cm ( to 1 dec. place )
Answer:
1. 31
Step-by-step explanation:
a² + 8² = 32² (<em>figure out what 8² and 32² equal</em>)
a² + 64 = 1024 (<em>subtract 1024 - 64</em>)
a² = 960 (<em>find the square root of 960</em>)
√960 = 30.98 = 31 (<em>round to the nearest whole number</em>)
Hi Pls find attached file
To find :-
- What percent is 700 paise of 7 rupees .
Solution :-
As we know that,
→ ₹1 = 100 p
So ,
→ 700p = ₹ 700/100
→ 700p = ₹ 7
Now let's calculate % , as ;
→ 700p / ₹7 * 100 %
→ ₹7/₹7 *100 %
→ 1 *100%
→ 100%
<u>Hence</u><u> </u><u>7</u><u>0</u><u>0</u><u>p</u><u> </u><u>is </u><u>100%</u><u> </u><u>of </u><u>₹</u><u>7</u><u> </u><u>.</u>
I hope this helps.
length of the slide is lets say 'l' the height (h) opposite to the angle 28 is found by h=l*sin28 where sin28=0.47 approximately h=4.5*0.47 h=2.115m
