00:00 - 00:59 | best friend as questions given on level ground a vertical rod 12 feet tall cast a shadow for feet long and at the same time a nearby vertical flagpole cast a shadow 12 feet long how many feet tall is the flagpole to find the height of the then this is the light and this is that is long and its shadow is 4 feet long and the part of life and it is given that there is another vertical flagpole let this |

01:00 - 01:59 | the another flagpole that distances that its length and it is given that its shadow is 12 feet long and this is the angle and we know that tan theta is always equal to perpendicular divide by using this you will find the value of 10 in the smaller triangle with Android 10 theta is equal to perpendicular lines 12 and 20 / / and put the large triangle which Android perpendicular is X and bases that then we can write 10 theta is equal to |

02:00 - 02:59 | divide by using this equation you will find the value of x we can cancel this well with this 4 then become 3 is equal to 12 volt to the inside planetarium in multiplication x is equal to 3 into 12 that is 36 it it mean another platform length is 36 B if we compare our answer with given options we will get it thank you |

**Review of some terms**

**Measure of an Angle**

**Trigonometric Ratios**

**Trigonometric ratios are same for same angle**

**Relation between trigonometric ratios**

**In a `Delta ABC`; right angled at A; If AB=5;AC=12 and BC=13; find sin B;cosC and tanB**

**In a `Delta ABC`; right angled at B; If ` sin A = 3/5`; find `cos A; tan A; sec A and Cosec B.**

**In a `Delta ABC`; right angled at B; If ` sin A = 3/5`; find `cos A; tan A; sec A and Cosec B.**

**In a `Delta ABC`; right angled at B; If ` sin A = 3/5`; find `cos A; tan A; sec A and Cosec B.**

**Trigonometric ratios of `0^@ and 90^@`**
