Answer:
27
Step-by-step explanation:
Using PEMDAS, you will subtract first/ 14-5 = 9. Then we have the 3 and the 9 left. Multiply and you get 27
If you are looking to find the discounted price, you would multiply 89 by .15 to get 13.35. This is the amount that is taken off,o r 15 percent of 89. Subtract 13.35 from 89 to get 75.65 as the discounted price.
Answer:
B = 75°
Step-by-step explanation:
Using the Sine rule:
a / sin A = b / sin B = c / Sin C
a / sin A = b / sin B
20 / sin 48 = 26 / sin B
Cross multiply :
Sin B * 20 = sin 48 * 26
Sin B = (sin 48 * 26) / 20
Sin B = 0.9660882
B = sin^-1(0.9660882)
B = 75.036
B = 75°
Answer: C) angle 2 and angle 7
Imagine the parallel lines form the boundaries of river. Angles 3, 4, 5 and 6 are considered interior angles as they are in the river. Angles 1, 2, 7, 8, 9 and 10 are exterior because they're outside the river.
Angles 2 and 7 are on opposite sides of the transversal cut that I've highlighted in red (see diagram below). So that's why they're considered alternate. Combine "exterior" and "alternate" to get "alternate exterior"
