Understand the concept of a unit rate a/b associated with a ratio a:b with b ≠ 0, and use rate language in the context of a ratio relationship. For example, “This recipe has a ratio of 3 cups of flour to 4 cups of sugar, so there is 3/4 cup of flour for each cup of gallons of water.”How many cups of disinfectant are needed for 20 gallons of water so c is
Answer:
1 = 35
2 = 55
Step-by-step explanation:
so we know that between 1 and 2 it is 90 degrees we also know that angle 1 and the angel to the left of it make 180 degrees so do
180 - 90 = 90
this means the angle next to line 1 is also 90 degrees
then we would see that the 55 degrees the 90 degrees and angle 1 make 180 degrees so do
55 + 90 = 145
180 - 145 = 35 degrees so angle 1 is 35 degrees
then we would find angle 2
90 - 35 = 55 degrees so angle 2 = 55
hope this helps : )
Answer:
144.5
Step-by-step explanation:
Area of a triangle = one half of the base length times the height
The given base length is 17 cm and the given height is 17 cm
Hence, area = 
17 * 17 = 289
289 / 2 = 144.5
Area = 144.5cm²
