Answer:

x=15

Step-by-step explanation:

so we are given one angle 90, although x is used in both so you can add them. We know that the sum of angle measures in a triangle is 180 so the equation is: 90+6x=180

subtract 90 from both sides: 6x=90

divide by 6: x=90/6

simplify: x=15

800+900×25-65(89+5)-12÷67-7​
vlada-n [284]

Answer:

As there is Bracket lats solve it first but as there is '-' sign before the bracket sign in the bracket will change. so we will have,

'800+900×25-65(89-5)-12÷67-7'

Solving the bracket gives us:

'800+900×25-65(84)-12÷67-7'

Now avoiding the Bracket:

'800+900×25-5460-12÷67-7'

Now first we have to do MUltiplication, so we will get,

'800+22500-5460-12÷67-7'

Now let's do the division, so we will get,

'800+22500-5460-0.17-7'

Now lets do the additions and subtractions we will get,
