I believe A is the answer
Answer: 15 in
Step-by-step explanation:
Area of triangle = 1/2 * base * height
A= 0.5 * 3 * 10
A = 15 in
Answer:
1) Antonio's statement
2) <A = 123
Step-by-step explanation:
1) Antonio's statement is incorrect. This is because the opposite angles of a quadrilateral add up to 180°. Erin was incorrect because the opposite angles of this quadrilateral are unequal.
2) 2x+7+5x-2 = 180° (opposite angles of quadrilateral)
Now
7x+5 = 180
7x = 175
x = 25
<A = 5x-2
= 5(25)-2
= 125-2
= 123
Answer:
w=63, x = 86, y=38 and z = 25 degrees
Step-by-step explanation:
w + 117 = 180
so w = 180 - 117 = 63 degrees.
x = 180 - 63 - 31 = 180 - 94
= 86 degrees
y = 180 - 86 - 56 = 180 - 142
= 38 degrees
z = 180 - 117 - 38 = 180 - 155
= 25 degrees
