Answer:

2. angle BAD is equal to angle DCB?

3. angle CBA is equal to angle ADC, then

4.triangle BEA is equal to triangle DEC and triangle BEC is equal to DEA

Step-by-step explanation:

since line BCD is equal to line DAB

AND line CBA is equal to line ADC

and because BEA triangle equals DEC, angles BEA and DEC are congruent

and angle BEC is equal to DEA

and yeah your right, it would be supplementary.

In jungle one year monkey population increased in a ratio of 8:7 but the next year it is decreased in the ratio of 16:17.Tell ho

AleksAgata [21]

Answer:

Population of monkeys after 2 years = 3200

Step-by-step explanation:

Total number of monkeys at the start = 2975

Increase ratio of monkey population one year = $8:7$

∴ New population of monkeys after 1 year= $Total\ population \times Increase\ ratio = 2975\times \frac{8}{7} =3400$

Decrease ratio the next year = $16:17$

∴ Population of monkeys after 2 years= $New\ population \times Decrease\ ratio = 3400\times \frac{16}{17} =3200$

of the following options, what could be a possible first step in solving the equation 8x 3 = 2x − 15? adding 8x to both sides of

sesenic [268]

Adding 15 to both sides. In order to get it to the opposite side of the equal sign, you must do its opposite. You can't add 8x to both sides, because the opposite of positive 8x is negative 8x and that's not what they're asking. The opposite of negative 15 is positive 15, so it works. Opposite of positive 3 is negative three, and they're wanting a positive, so it will not work. Adding 2x wouldn't work, because it's already positive..
