add the 2 angles: 89+80= 169
subtract 180-169= 11
11° is the measurement of the final angle
do sin(80)=12/x
x(sin(80))=12
plug in on calculator:
x=12/(sin(80))
y - 90 - 1/9 = 12.45 Step-by-step explanation: i think so if im incorrect
y=8(x^2 + 4x + 4) +17 + -32
Simplify:
y = 8(x^2 + 4x + 4) + 15
Use distributive property:
y = 8x^2 + 32x +32 - 15
Simplify:
y = 8x^2 + 32x +17
Complete the square using form ax^2+bx+c:
a = 8, b = 32, c = 17
vertex form = a(x+d)^2+e
d = b/2a and e = c-b^2/4a
d = 32/2*8 = 32/16 = 2
e = 17 - 32^2/4*8 = 17-1024/32 = 17-32 = -15
Vertex form = y = 8(x+2)^2 + -15
Answer:
Add 5 to 13.
Step-by-step explanation:
You would use brick wall to solve.
Step-by-step explanation:
Since line NL is not necessarily congruent to MQ (labelled with different congruent marks), triangle NLM is not congruent to triangle MQP.
Instead, triangles NLM and QPM are congruent.
