Space-limited inverted V advice needed

I want to put up a 40M inverted vee.

Will use a 52' tower against the house that can hold the apex, but can only get the ends 50' apart at 10' off the ground - at the house roof corners. This calculates to about a 61 degree angle at the apex, which is a lot less than 120 deg I understand is optimum or 90 deg minimum.

Might I be wasting my time with this angle? Any comments appreciated.

I would suggest getting it as high as possible. If you have supports 50 feet apart, you can run support ropes roughly 14' long to get the antenna ends about 20' in the air. I'd suggest starting out with about 34' on each side, which is a little more than the usual 66 feet for a flat top dipole.

The SWR bandwidth narrows, but this may be better than the alternatives.
