When a number and letter are together, it means multiplication.
So, it is read as "23 times f".
The measure of ABD=180°- 54°=26°
and then the measure of ADB= x
and x + 26° + 28°= 180°, sum of anlgle in a triagle property
it means x= 180°- 26-28=126°
application of sinus law in the triangle
sin 28 / BD = sin 126/ AD = sin 26/ 25 so we can deduce that
AD= 25sin126 / sin26= 46.12
let 's consider the triangle ADC, so for finding h, we have sin 28 = h / AD
and then h = AD x sin28=21.65

Hi there! Bananas are sold at $0.80 per pound and grapes are sold at $2.50 per pound. To find out how much Mrs. Anderson spent overall, we need to find out how much she spent with each item and then add them up together. She bought 4.3 pounds of bananas and 2.1 pounds of grapes. Let's multiply each of them by the unit prices there are. 4.3 * 0.8 is 3.44 and 2.1 * 2.5 is 5.25. 3.44 + 5.25 is 8.69. There. Mrs. Anderson spent a total of $8.69.
Answer:
a
Step-by-step explanation:
sec (thita) = squrt (5)
squaring on both sides:
sec^2 (thita) = 5 - equation 1
1 + tan^2 (thita) = 5
tan^2 (thita) = 4
tan (thita) = 2.
= tan (thita) - squrt(5)sin(thita)
= 2 - squrt(5) x 2/ squrt(5)
= 0
from eqn - 1
sec(thita) = squrt(5)
cos(thita) = 1/ squrt(5)
sin(thita) = squrt ( 1- 1/(squrt (5))^2)
sin(thita) = 2/ squrt(5) .
