Answer:
You're correct. x= 28
Step-by-step explanation:
2x - 49 + x + 90 + 55 = 180
2x - 49 + x + 145 = 180
3x - 49 + 145 = 180
3x + 96 = 180
3x + 96 - 96 = 180 - 96
3x = 84
3x/3 = 84/3
x= 28
Answer:
<h2>

Step-by-step explanation:
<h2>capital of Peru. It is the country's commercial and industrial centre. Central Lima is located at an elevation of 512 feet (156 metres) on the south bank of the Rímac River, about 8 miles (13 km) inland from the Pacific Ocean port of Callao, and has an area of 27 square miles (70 square km).</h2>
Answer:
pythagoras theorem
so we have a and b
12 and 9
so ...
take the square root to find c, since 225 is c^2
so √225 = c = 15
M < 2 and m < 3 are supplementary angles which add up to 180 degrees.
< 2 + < 3 = 180
3x + 17 + 5x - 21 = 180
8x - 4 = 180
8x = 180 + 4
8x = 184
x = 184/8
x = 23
m < 2 = 3x + 17 = 3(23) + 17 = 69 + 17 = 86 degrees
m < 3 = 5x - 21 = 5(23) - 21 = 115 - 21 = 94 degrees
m < 1 and m < 2 are corresponding angles....they are equal.
so m < 1 = 86 degrees <===
Answer:
Step-by-step explanation:
74+47=x(sum of two interior opposite angle is equal to the exterior angle formed)
121=x
