Answer» ong>Given, Heights of two poles = 8m and 14M Distance between their top = 10m To find, The distance between their feet. Solution, If we imagine a vertical straight line which starts from the top of the first pole and perpendicularly ends on a certain point on the second pole, then the second pole is DIVIDED into two segments. The Length of the upper segment of the second pole from that IMAGINARY point will be = (14-8) = 6m Now, we can easily imagine a right angled triangle in this case, which has, Base = Distance between two poles = Let, X m Height = Upper segment of the second pole = 6m Hypotenuse = 10m According to the Pythagoras theorem, (10)²=(x)²+(6)² 100 = x²+36 x² = 100-36 x² = 64 x = 8 HENCE, the distance between their feet will be 8m.

Two poles of 8m and 14m stand upright on a plane ground. If the distance between two tops is 10 m. Find the distance between their feet.

Answer»

ong>Given,

Heights of two poles = 8m and 14M

Distance between their top = 10m

To find,

The distance between their feet.

Solution,

If we imagine a vertical straight line which starts from the top of the first pole and perpendicularly ends on a certain point on the second pole, then the second pole is DIVIDED into two segments.

The Length of the upper segment of the second pole from that IMAGINARY point will be

= (14-8) = 6m

Now, we can easily imagine a right angled triangle in this case, which has,

Base = Distance between two poles = Let, X m

Height = Upper segment of the second pole = 6m

Hypotenuse = 10m

According to the Pythagoras theorem,

(10)²=(x)²+(6)²

100 = x²+36

x² = 100-36

x² = 64

x = 8

HENCE, the distance between their feet will be 8m.

Answer» ong>Answer: SINA= 15/17. SECA= 17/8 Step-by-step explanation: GIVEN, base= 8 perpendicular=15 using phythagorous, (H)²= (b)²+(p)² h= √(b)²+(p)² h= √ 8²+15² h= √64+225 h= √289 h= 17 so sinA= p/h = 15/17 secA=h/b = 17/8

4and tan A.4. Given 15 cotA= 8, find sin A and sec A.13

Answer»

ong>Answer:

SINA= 15/17. SECA= 17/8

Step-by-step explanation:

GIVEN, base= 8

perpendicular=15

using phythagorous,

(H)²= (b)²+(p)²

h= √(b)²+(p)²

h= √ 8²+15²

h= √64+225

h= √289

h= 17

so sinA= p/h = 15/17

secA=h/b = 17/8
