Answer:
∠8 * 4 = ∠7 ----------------(1)
∠8 + ∠7 = 180 ------------(2)
Taking the value of ∠7 from (1) and using it in (2):
<u><em>∠7 = 4 * ∠8</em></u>
<u><em /></u>
∠8 + ∠7 = 180
∠8 + (4 * ∠8) = 180
∠8 + 4∠8 = 180
5∠8 = 180
∠8 = 36° ---------------(3)
Using the value of ∠8 from (3) in (2):
∠8 + ∠7 = 180
36 + ∠7 = 180
∠7 = 144° and ∠8 = 36°
Answer:Type of Angle Description
Acute Angle is less than 90°
Right Angle is 90° exactly
Obtuse Angle is greater than 90° but less than 180°
Straight Angle is 180° exactly
Step-by-step explanation:
Answer:
line of best fit
Step-by-step explanation:
line of best fit is NOT a method for solving a quadratic equation.
Rest of all the methods are used for solving a quadratic equation.
Answer: 1) The value of the 3 in option A is 10x the value of the 3 in option B
2) Option A has the 3 in the ones places, Option B has the 3 in the tenths place
Step-by-step explanation:
Cross multiply
5/8 and 8/10
5x8=40
8x8=64
40 does not equal 64 so not proportional
