Angle 1 and angle 2 are a linear pair. m of angle 1=x-35 and m of angle 2 =x+83. find the measure if each angle

Angle 1 = 31 degree

Angle 2 = 149 degree

Step-by-step explanation:

We have given that :

M of Angle 1 = x-35 and m of Angle 2 = x+83

Angle 1 and Angle 2 are linear pair

linear pair means the sum of angle is 180  

⇒ Angle 1+ Angle 2 = 180

⇒ x-35 + x+83 = 180

⇒ 2x+48 =180

⇒ 2x= 132

⇒ x= 66

Now put the values of x in both the angle

Angle 1 = x-35 = 66-35 = 31 degree

Angle 2 = x+83 = 66+83 = 149 degree

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.  

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
