Question
In the figure BD = CD = AC, ∠ABC = 27 ° , ∠ACD =
y. Find value of x.Solution
∠BCD = ∠DBC = 27° (BD = CD)                 ∠BDC = 180° – (27° + 27° )= 126°                 ∠ADC = 180° – ∠BDC = 54°                 ∠DAC = ∠ADC = 54° (CD = AC)                 x = 180° – (54° + 54° ) = 72°
1219.98 ÷ 30.48 × 15.12 = ? × 2.16
What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)...
`1804/898-:99/699xx749/751=?`
(√845 ×19.932+ √4230 ×14.385)/(√1765 ×4.877 ) = ?
Direction: Please solve the following expression and choose the closest option
`(13.022)^(2)+ (42.93)^(2)-(53.125)^(2)+(192.33xx14.88)=?- (88.44)^(2)- (42.03 xx 23.12)`
√49 + 6.66% of 1725 + 22² = ?² - √361Â
